Air Pollution Control Equipment: Types and Applications

Chapter 1: Understanding Air Pollution Control Equipment: Functionality and Key Considerations for Selection

The term "air pollution control equipment" refers to advanced systems used to curb the discharge of various solid and gaseous pollutants into the atmosphere, primarily originating from industrial emissions via exhaust stacks or chimneys. These systems are classified into two main categories: those that target acidic gas emissions and those designed to manage particulate matter emissions effectively.

How Does Air Pollution Control Equipment Function?

Air pollution control technologies primarily function through three core methods:

1. Chemical Alteration: This method involves converting a dangerous chemical into a non-reactive form. A common approach is flue gas desulfurization. Additionally, techniques like selective catalytic reduction and non-catalytic reduction are used to manage nitrogen oxide (NOx) emissions by transforming them into molecular nitrogen (N2). Professionals might also employ biofiltration, thermal oxidation, or catalytic oxidation techniques.
2. Hazard Elimination: The most widespread and straightforward method for air cleanliness involves removing hazardous substances from air. Although various techniques exist, air filter systems are frequently utilized for this purpose.

Monitoring Air Pollution Control Equipment

Considering that operational conditions and environments vary substantially across different facilities, choosing suitable monitoring equipment or methodologies involves more complexities than merely comparing performance metrics and costs. Each facility and installation has specific monitoring needs, influenced by several critical factors.

Essential Considerations for Selecting Air Pollution Control Equipment

• It is vital to examine the physical and chemical properties of pollutants and the waste gas stream before making a purchase decision.
• Ensure the monitoring equipment is compatible with the system it will serve; carefully consider regulatory or permitting constraints along with associated reporting needs.
• Decisions regarding where and how samples are collected, processed, and managed affect equipment choice.
• The equipment should meet established standards for calibration and accuracy.
• Quality remains the top priority when selecting monitoring tools; ensure that it aligns with quality control requirements.
• Given that all equipment requires regular maintenance, check that maintenance services are easily accessible.
• The monitoring infrastructure should not interfere with the safety and management systems in place.

These factors collectively assist in acquiring the monitoring equipment best suited for specific operational requirements.

Chapter 2: What Is The History of Air Pollution Equipment

The Industrial Revolution marked a pivotal shift in manufacturing and human activity, but one major consequence was a significant rise in air pollution stemming from the combustion of fossil fuels in industrial processes. As factories, power plants, and other industrial facilities proliferated, excessive exploitation of natural resources—including wood, coal, water, and land—led to a dramatic increase in emissions of harmful pollutants such as sulfur dioxide (SO₂), nitrogen oxides (NO_x), carbon monoxide (CO), and particulate matter (PM).

By the mid-20th century, the serious health and environmental impacts of unchecked industrialization and poor air quality became increasingly evident around the world. For example, in 1948, severe smog in Donora, Pennsylvania, resulted in the deaths of 20 people and illnesses in more than 7,000 others—largely due to emissions from local zinc works and steel mills. In 1952, London experienced "The Great Smog," a dense, choking fog formed when sulfur dioxide, particulate matter, and coal-burning gases combined with weather conditions. This catastrophic pollution event resulted in the deaths of 12,000 people and caused respiratory distress for countless more individuals and animals over a five-day period. In 1984, Bhopal, India, became the site of another infamous air pollution disaster; a gas leak at the Union Carbide chemical plant released toxic methyl isocyanate into the air, injuring or sickening between 150,000 and 600,000 residents and killing nearly 4,000 workers.

These tragedies, along with increasing scientific evidence linking air pollution to diseases such as asthma, lung cancer, and cardiovascular conditions, prompted governments worldwide to introduce various clean air regulations and environmental protection standards. For instance, the UK government responded with the first Clean Air Act in 1956, prohibiting coal burning in cities and establishing emission limits. The United States followed with the Clean Air Act of 1970, fundamentally changing the regulatory landscape for industrial air emissions and setting strict national air quality standards.

Following the implementation of clean air laws, many industries adopted advanced air pollution control equipment to reduce emissions and comply with environmental regulations. Companies implemented a range of air filtration and abatement technologies—including baghouse dust collectors, electrostatic precipitators, catalytic and thermal oxidizers, and wet and dry scrubbers—to capture and remove airborne contaminants like volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and fine particulates.

The electrostatic precipitator, for instance, represents one of the earliest and most influential pollution control innovations. First conceptualized by German mathematician Dr. M. Hohlfeld in 1824 and later patented by Professor Frederick Gardner Cottrell in 1907, this device uses electrically charged plates to attract and trap airborne particles. Originally intended to recover sulfuric acid mists, electrostatic precipitators have since been widely adopted across power generation, cement production, and chemical processing industries for their efficiency in capturing fine particulates.

The Clean Air Act Amendments of 1990 further expanded regulatory oversight, mandating regular monitoring and reporting of specific criteria pollutants and hazardous emissions from stationary sources. Advanced continuous emissions monitoring systems (CEMS), coupled with accurate sampling equipment and real-time data logging, are now vital for facilities to demonstrate compliance with EPA, OSHA, and other regulatory agencies’ standards. Emissions monitoring not only helps with licensing and environmental audits, but also enables proactive maintenance, operational optimization, and the evaluation of installed air pollution control solutions.

Through the dedication, research, and advocacy of environmental scientists, engineers, and policymakers, significant progress has been made in reducing VOCs, HAPs, and particulate emissions in recent decades. However, as climate change emerges as a global priority, carbon emissions (CO₂ and greenhouse gases) have come under increasing scrutiny. Modern regulations now focus on lowering industrial carbon footprints, advancing sustainable air abatement solutions, and promoting energy-efficient pollution control equipment.

In response to evolving standards and the increasing complexity of regulatory requirements, manufacturers may need to go beyond traditional air pollution control systems like incinerators or oxidizers. Advanced solutions such as high-efficiency mist collectors, multi-stage wet and dry scrubbers, modular electrostatic precipitators, regenerative thermal oxidizers (RTOs), and hybrid systems that integrate various filtration and abatement technologies are now at the forefront of industrial air quality management. When selecting pollution control equipment, facility owners and environmental engineers should consider factors like process emissions profile, existing infrastructure, operational costs, local and federal emission limits, as well as the potential for future scalability and integration with energy recovery systems.

Understanding the evolution and application of air pollution control equipment not only supports regulatory compliance but also protects the health of workers, communities, and the environment—creating a cleaner, safer, and more efficient industrial landscape for future generations.

Leading Manufacturers and Suppliers

Chapter 3: What Are The Types of Air Pollution Control Equipment

As sustainability and industrial air quality standards gain global momentum, nearly every modern manufacturing or processing facility implements some form of air pollution control equipment to minimize emissions of volatile organic compounds (VOCs), hazardous air pollutants (HAPs), particulate matter (PM), and greenhouse gases (GHGs). These systems are vital for maintaining compliance with environmental regulations, such as those enforced by the EPA and other government agencies through regular inspections, certifications, and monitoring of stack emissions.

Air pollution control equipment manufacturers provide a diverse range of engineered solutions tailored to address the specific air quality challenges found in industries such as chemical production, power generation, pharmaceuticals, automotive, mining, metal fabrication, and food processing. Selecting the optimal air quality control system depends on factors such as emission composition, process temperature, exhaust stream flow rates, and facility layout.

Carbon Adsorbers

Among the most effective VOCs removal technologies available, carbon adsorbers function by channeling contaminated air over or through a bed of activated carbon. This carbon media traps and retains VOCs, odors, and other airborne toxins, while allowing purified air to pass through. Carbon adsorbers excel at treating emissions containing organic solvents from industries like printing, painting, and chemical manufacturing.

Various adsorbent media can be used to optimize performance for specific applications, including lithium hydroxide, sodium hydroxide, amines (such as monoethanolamine), minerals, and zeolites (e.g., serpentinite). Routine replacement or regeneration of carbon beds ensures continued high-efficiency pollutant removal and cost-effective operation.

Air Scrubbers

Air scrubbers are advanced air purification systems that capture airborne contaminants, remove particulate matter, and treat toxic or corrosive gases in industrial emissions. By filtering or cooling the airstream as it enters, these systems can effectively reduce harmful particulates, improve indoor air quality, and support compliance with environmental standards. Air scrubbers come in both wet and dry configurations, distinguished by their method of contaminant removal. They are commonly used in chemical processing, petroleum refining, and waste incineration industries where air pollution control is critical.

Wet Air Scrubbers

Wet scrubbers use water or aqueous solvent sprays to capture and neutralize pollutants such as sulfur dioxide (SO₂), ammonia, and particulate matter from industrial exhaust streams. Their superior removal efficiency makes them ideal for controlling emissions from applications generating acidic gases, odors, and dust, including wastewater treatment, pulp and paper, and chemical manufacturing facilities. Wet scrubbers often form a critical component of multi-stage pollution control systems designed to address complex emission profiles.

In operation, contaminated air enters the scrubber’s lower chamber, then passes upwards into a packed bed where it is thoroughly mixed with fine solvent mist. A mist eliminator removes residual droplets, ensuring only clean air exits the stack. The solvent’s ability to absorb targeted pollutants depends on factors such as its chemical composition, pH, and ionic charge, which influence bonding with inorganic contaminants.

The adaptability of wet scrubbers allows for removal of multiple pollutant classes—including odors, gases, mists, sulfides, and acidic vapors—making them a preferred air emissions control technology for facilities with fluctuating or mixed pollutant loads.

Dry Air Scrubbers

Dry scrubbers employ chemical reagents—such as lime or sodium bicarbonate—to react with and neutralize gaseous pollutants in industrial exhaust streams. As the process does not require liquid solvents, there is no liquid waste, thereby minimizing disposal and operational costs. Dry scrubbers are frequently integrated into flue gas desulfurization systems and are effective for capturing acidic vapors and soluble hazardous compounds, especially in applications with lower exhaust moisture or volume.

The reaction products—primarily salts and other neutralized byproducts—are captured in a filter system or incinerated by high exhaust temperatures, making dry scrubbers both efficient and eco-friendly for air quality management.

Electrostatic Precipitators

Electrostatic precipitators (ESPs) are sophisticated, filterless devices that use electrically charged plates or wires to extract solid particles—such as dust, soot, ash, smoke, and fine fumes—from industrial gas streams. ESPs offer exceptionally high fine-particle removal efficiencies, making them indispensable for controlling emissions from power plants, manufacturing, steel mills, and any process relying on combustion of fossil fuels.

Contaminated exhaust gases pass through high-voltage electrodes, imparting a static charge to airborne particulates. These charged particles are attracted to collector plates of the opposite polarities, where they accumulate for safe removal and disposal. Electrostatic precipitators are a mainstay of industrial air purification and emission control, reducing health risks, environmental impact, and ensuring compliance with stringent clean air standards.

Furthermore, ESPs can be configured to target a particular size range of particles, adapting to variations in dust loads or process changes. Their modular design also makes them scalable for large facilities or high-throughput operations.

Oxidizers

Thermal oxidizers—sometimes referred to as incinerators—destroy dangerous airborne chemicals and organic compounds through controlled high-temperature combustion. These devices transform HAPs and VOCs present in industrial gases into water vapor and carbon dioxide, reducing the release of toxic substances. With advanced safety mechanisms and real-time monitoring, oxidizers are extensively used in large-scale manufacturing, chemical production, and pharmaceutical plants for regulatory compliance and health protection.

Oxidizer system variations (including catalytic oxidizers and regenerative oxidizers) offer trade-offs between energy recovery, operational costs, and compatibility with different pollutants. Modern systems often feature heat recovery solutions—such as air-to-air or ceramic heat exchangers—to maximize fuel efficiency and lower operating expenses while maintaining high destruction rate efficiency (DRE). Wet electrostatic precipitators (WESPs) or downstream scrubbers may be integrated to address the removal of acid gases or particulate matter generated during the oxidation process.

Catalytic Oxidizers

Catalytic oxidizers run at lower operating temperatures than thermal oxidizers, leveraging catalyst-coated media such as platinum or palladium to accelerate the breakdown of VOCs and convert hazardous organic gases into environmentally safe compounds. This process not only minimizes fuel usage but also extends the lifespan of pollution control equipment while achieving regulatory emission limits. These systems are widely adopted in chemical processing, paint and coating, and printing industries where VOC destruction is a priority.

Available in regenerative and recuperative configurations, catalytic oxidizers can recycle heat—reducing the total energy demand of the air emissions control system. Their modularity allows seamless integration into both new and existing industrial pollution control infrastructures across diverse sectors.

Regenerative Thermal Oxidizers

Regenerative thermal oxidizers (RTOs) maximize energy recovery by using ceramic heat transfer beds to preheat incoming waste gases via a cyclical process. This technology enables RTOs to achieve DRE rates of over 99% for VOCs, HAPs, and odorous emissions, while dramatically reducing natural gas or fuel input. RTOs are particularly effective in handling high-volume, low-VOC-concentration airstreams typical of processes such as painting, coating, and printing.

Recuperative Oxidizers

Recuperative oxidizers utilize traditional shell-and-tube or plate-type heat exchangers to recover energy released from oxidized gases, pre-heating incoming streams and enhancing overall efficiency. These oxidizers are optimal for applications requiring high thermal efficiency with variable process temperatures, such as chemical reactors, solvent abatement systems, and large-scale manufacturing plants. The integration of heat exchangers facilitates significant reductions in operating costs and heat losses.

Direct-Fired Thermal Oxidizers

Direct-fired thermal oxidizers (DFTOs), also known as afterburners, offer a straightforward configuration for the destruction of hydrocarbon emissions. Without the inclusion of heat recovery systems, these oxidizers achieve rapid pollutant breakdown by maintaining high dwell times and elevated temperatures, making them suitable for processes generating concentrated organic vapors or intermittent emission spikes. With destruction efficiencies reaching up to 99%, DFTOs represent a proven solution for rapid compliance with air emission standards at minimal capital cost.

Flameless Thermal Oxidizers (FTO)

Flameless thermal oxidizers (FTOs) introduce air and waste gases into preheated, non-catalytic ceramic beds to ensure thorough mixing and uniform temperature distribution. By preventing the formation of temperature gradients and hot spots, FTOs optimize the thermal destruction of pollutants like VOCs and maintain ultra-low emissions of nitrogen oxides (NOx). These systems are often adopted in sensitive environments where strict emission limits and process consistency are paramount. When waste heat is insufficient, burners or electric heaters supplement the necessary thermal energy for reliable system operation.

Mist Collectors

Mist collectors, sometimes called moisture-eliminator filters or demisters, are specially engineered to remove submicron droplets, vapor, and oil mist from exhaust gas streams. Their high filtration efficiency makes them ideal for capturing fine aerosols in metalworking, machining, pharmaceutical, and food processing industries. Mist collectors leverage filter media—often comprised of dense mesh or coalescing pads—to consolidate liquid particles for collection and recovery, often maintaining over 99% efficiency for droplets below 0.3 micron in diameter.

Mist collectors are best suited for non-particulate exhaust applications and environments where gas streams remain below 120 °F (48 °C). For gas streams carrying abrasive particulates or extremely high temperatures, alternative air pollution control technologies are recommended.

Cyclone Dust Collectors

Also referred to as cyclonic separators, cyclone dust collectors efficiently eliminate heavy dust, sawdust, woodchips, and non-fibrous particulates from industrial exhaust without the need for disposable filter media. These systems induce a high-velocity spiral in the gas flow, generating centrifugal force that propels particulate contaminants against the chamber walls for collection. Cyclones are popular as primary dust collectors in woodworking, mineral processing, cement production, biomass energy, and foundry operations. For fine particulate or submicron dust removal, they are often paired with secondary filtration technology, such as baghouses or cartridge collectors.

This modular approach increases air quality system reliability and allows facilities to meet even the most demanding particulate emission limits.

Catalytic Reactors

Selective Catalytic Reduction (SCR) systems, or catalytic reactors, represent the industry best practice for reducing high levels of nitrogen oxides (NOx) in fossil fuel combustion exhaust. Industrial SCR units inject ammonia into the flue stream, allowing reactive surfaces with catalysts to convert NOx to harmless nitrogen and water vapor. These reactors may also reduce other gaseous pollutants, including carbon monoxide (CO) and VOCs, as in the case of the three-way catalytic converters used in automotive emission control.

While SCR technology offers over 90% NOx reduction and can attain up to 99.99% efficiency for select gases, it is generally unsuitable for exhaust flows with high dust or particulate content and is comparatively costly compared to filtration-based pollutant control. For integrated air pollution control, SCR units are often combined with particulate abatement stages, such as baghouses or ESPs, in power plants and other stationary combustion sources.

Biofilters

Biofilter systems harness the metabolism of naturally occurring microorganisms—primarily bacteria and fungi—to biologically degrade water-soluble chemicals, organic HAPs, and VOCs from contaminated air. Unlike combustion-based control equipment, biofilters do not generate hazardous byproducts such as NOx or CO. Instead, they convert pollutants into benign end-products, delivering over 98% removal efficiency for various organic contaminants. Typical installations include compost-based beds or engineered synthetic media, and biofilters are optimal for industries such as municipal wastewater plants, food processing, composting, and certain chemical production operations.

By understanding the performance characteristics and application requirements of each air pollution control equipment type, companies can engineer integrated air quality management systems that address evolving regulatory, operational, and environmental challenges—protecting employees, communities, and the global climate. When selecting the best emission control solution, factors such as contaminant type (organic vs. inorganic), particulates vs. gases, process flow rates, operational temperature, regulatory limits, and cost of operation must all be carefully considered. Consulting with experienced air quality engineers and evaluating third-party equipment reviews can help ensure compliance and optimal performance of your facility’s pollution control system.

Chapter 4: Applications and Maintenance of Air Pollution Equipment

Applications of Air Pollution Control Equipment

Industrial air pollution control equipment is crucial and must be prioritized. Almost every industry contributes to environmental pollution through its operations. Sectors such as petroleum, oil, coal, metal, chemical, and waste management are among the major contributors to toxic emissions.

Industrial activities—including raw material extraction, product manufacturing, site and machinery maintenance, and transportation—inevitably generate pollution. Burning fossil fuels releases volatile hydrocarbons, while the use of wood and coal as fuel results in carbon dioxide and sulfur dioxide emissions. Additionally, automobiles contribute significantly to harmful carbon emissions. Each industrial process emits pollutants that contaminate the air, soil, or water.

1. Reducing the discharge of dangerous gasses and stopping the spread of air and water pollution are the objectives of industrial air pollution control equipment.
2. Protect any remaining natural resources for future generations.
3. Reduce pollution-related risks to health that can be inhaled or otherwise ingested.

Non-industrial air pollution control technologies are also used in homes, cars, and other mobile environments. For example, home air conditioners often feature filtration systems that remove impurities such as pet dander, allergens, mold spores, and dust.

Additionally, precision filtration systems help reduce vehicle emissions from engines, exhaust systems, and air conditioning units.

Maintenance of Air Pollution Control Equipment

1. By doing routine tests all year long, you can prevent sudden shutdowns. Make a monthly schedule for testing the alarm system, intake valves, or control components. Manufacturers can assist in identifying faults before they impact output by ensuring the equipment is operating as planned. These tests can also guarantee the accuracy of the emission values used to meet EPA regulations.
2. Unwanted debris and dirt can accumulate inside the unit over time, reducing how well the system functions. Manufacturers can prolong the life of the equipment by designating specific days for thorough equipment cleanings. Consistent checks ensure that equipment goes smoothly without being inspected, regardless of whether the equipment needs a thorough cleaning every time.
3. In some circumstances, the machinery can need replacement components or the help of a professional in pollution control units. Adding a yearly or biannual visit with an expert can help manufacturers discover bigger concerns concealed from the untrained eye, even if the equipment appears to function well. In addition, manufacturers can save costs related to employee training on difficult repairs by using maintenance specialists.

Chapter 5: What Are Continuous Emission Monitoring Systems (CEMS)

Many facilities use continuous emissions monitoring systems (CEMS) to track, manage, and report emissions. These systems utilize various instruments to measure the concentration of particulate matter and gaseous chemicals at specific points, often in stacks or ducts. They also assess physical properties of waste gas streams, such as opacity. The New Source Performance Standard (NSPS) and the New Source Review (NSR) require emissions monitoring at major pollution sources, and certain EPA regulations also mandate continuous emissions monitoring.

In addition to parametric monitoring, continuous emissions monitoring helps technicians comply with Compliance Assurance Monitoring (CAM) regulations.

Parametric Monitoring

Parametric monitoring measures emissions by tracking key parameters related to the operation of process or air pollution control equipment. This method uses pollutant emission levels and monitored control parameters to assess compliance. The adoption of CAM regulations has increased the acceptance of parametric monitoring, as it offers a more flexible and cost-effective approach to demonstrating compliance.

Chapter 6: What Are Some Air Pollution Prevention Tips?

1. Use public transport whenever possible. For example, a bus can carry about 40 to 50 people at a time, while cars can only carry approximately one to four. Therefore, bus transit is better for the environment.
2. Use smart air filtering technology. Pollution can also enter indoor spaces. Consider getting an indoor air pollution control system. These systems keep the home environment clean while ensuring safe living for the user and their loved ones.
3. Use clever waste management strategies. People's bad behaviors are to blame for the increase in air pollution. As a result, it is important to dispose of waste responsibly and follow legal requirements.
4. To prevent the release of toxic chemicals and other pollutants into the environment, industries should implement sound waste management strategies.
5. Adopt eco-friendly habits. People and corporations should adhere to practices that have no negative effects on the environment.
6. Create a maintenance schedule for the equipment that controls pollutants and follow it. For the greatest performance, industrial and domestic pollution control equipment must be serviced periodically.
7. Avoid using products containing chemicals. Products with chemicals should be used sparingly or outside the house. Examples include paints and perfumes. Utilizing goods with low chemical content and organic qualities is another option.
8. Lastly, implement afforestation by planting and cultivating as many trees as possible. The act of planting trees improves the ecosystem greatly and aids in the release of oxygen.

Case Study

Utilizing Particulate Scrubbers for the Complex Air Needs of Food Processing Applications Food manufacturers face unique challenges in treating particulate emissions at their facilities as cooking and frying processes generate byproducts, such as grease or fine dust, in the air stream. The byproducts often contaminate the air or leave residues, posing food safety and air permit compliance concerns if ineffective control technologies are used; for  example, bag houses or air filters, which will likely foul. These additional complexities in food manufacturing process streams make it more challenging to determine the proper abatement technology for your food plant without leveraging outside expertise.

Pollution Systems Inc. (PSI) not only offers a diverse product line of wet scrubbers and oxidizers but is fully committed to understanding every detail of the process requiring  treatment. Considering each customer’s technical, operational, and business needs, including sustainability, allows PSI to confidently recommend and design a comprehensive  air control solution that suits the specified application. In food production processes, food safety and plant optimization are additional considerations prioritized in the system  design.

The following are two examples of how Pollution Systems tailors its Wet Particulate Scrubbers to the varying needs of food production processes. 

Case 1: Venturi Scrubber and Meat Production Plant 

After the unsuccessful implementation of Electrostatic Precipitators (ESPs) and air filters to treat grease-laden particulate exhaust from a pork sausage cooking operation, a food manufacturer collaborated with Pollution Systems to design an effective emission control solution for their process. Through a comprehensive evaluation, Pollution Systems engineers recommended implementing a Venturi Scrubber with a heated sump to treat the dirty exhaust stream.

PSI Venturi Scrubbers feature:

• A smaller equipment footprint, allowing for ease of installation to preexisting lines. 
• Handles particulate-laden air streams with high temperatures or that contain moisture and grease, which can occur in cooking, smoking, and frying processes. 
• Offer low operating costs due to their solid-state construction.
• Continuously discharge a portion of the water in the sump (blowdown) which decreases the frequency of cleaning. Integrating an additional clean-in-place manifold system can further reduce maintenance needs.

The venturi scrubber pulls the smoke and grease-laden air into the upper portion of the scrubbing vessel and introduces the stream to high-velocity recirculated water. Fine water droplets form, entrenching the particulate matter. The droplets flow to the lower portion of the scrubber, where velocity is reduced and causes the particulate droplets to fall into the collection sump. After passing through the mist eliminator, the remaining water separates from the particulate. The blowdown of the scrubbing liquid inhibits plugging or severe buildup within the scrubber.

Subsequent emissions testing and operational trials proved the unit effective and offered low maintenance while outperforming the ESPs. The successful implementation of the 
Venturi Scrubber System on the first sausage cooker line led the company to purchase additional units for the separate production lines. Since commissioning this unit, the 
company has relocated the original scrubber to another facility and continues to offer exceptional results after 15+ years of operation.

Case 2: Multi-Vane Scrubber and Cereal Production Facility

This food client had an undesirable experience with the constant cleaning and maintenance of their previous scrubber equipment due to the buildup of sticky food residues and subsequent biological growth, which made them skeptical about purchasing another particulate scrubber.

Recognizing the need for a more effective and sustainable solution for this particular application, Pollution Systems recommended their Multi-Vane Particulate Scrubber (MVS) 
Unit and implementing a pilot study with the client’s drying line process to demonstrate its effectiveness. Specifically designed for air pollution control in unique manufacturing 
settings, this technology boasts several features tailored to address common pain points in the food industry, such as:

• High reliability is essential in commercial food production, where downtime can result in significant financial losses and safety hazards. The pilot system is capable of withstanding the demands of batch and continuous operations.
• Ease of maintenance and self-cleaning properties are essential for food manufacturing plants, where they must meet strict food safety regulations. The MVS pilot unit utilizes advanced mechanisms to handle the unique challenges present in food production processes.

After the pilot study demonstrated success, the customer agreed to install a larger Multi-Vane Scrubber on one dryer line of their process to further test its capabilities alongside a competing unit. The results showed that the Pollution Systems unit outperformed the competitor scrubber system. Particulate matter was reduced significantly, eliminating the  need for manually removing buildup on the unit and surrounding surfaces. Moreover, the biological growth accumulating on the rooftop disappeared, contributing to improved operational efficiency and a cleaner, safer working environment.

Impressed by the performance of the MVS technology on the single dryer line, the customer decided to invest in Pollution Systems Multi-Vane Scrubbers for the rest of their 
facility. 

With the decision to install multi-vane scrubbers across their facility, Pollution Systems worked closely with the customer to ensure seamless integration into their existing 
processes. The commissioning and training provided enabled optimal use of the new technology and minimized downtime during implementation. Pollution Systems also incorporated monitoring and maintenance strategies to maximize long-term efficiency and ensure continuous compliance with environmental regulations and good business 
standards.

Solutions Tailored to the Unique Demands of Your Process

The successful implementation of particulate scrubber technology within these manufacturing facilities offers valuable insights into options that meet the current industrial air pollution control needs. Customized solutions that adapt to the unique challenges of each application are crucial in improving operational efficiency and sustainability.  dditionally, leveraging pilot programs to test new processes before full-scale adoption can help minimize risk and maximize cost savings.
