Odor Control Systems
Odor control systems remove unpleasant smells caused by gasses in industrial applications. They neutralize malodors, making them unavailable for olfactory senses to pick them up, thus improving working conditions. They are more effective than masking processes, which merely cover a bad smell with a stronger one as a temporary solution. They are often used in the waste industry, in landfills, solid and liquid waste management and sewers. In facilities that produce large amounts of methane such as pulp and paper plants or livestock processing, mist collectors and oxidizers are used as odor control systems. Air handling equipment, chemical manufacturing, and pesticide and herbicide manufacturing also use odor control systems in their facilities.
There are many different methods of controlling odors in industrial settings. Carbon filters, caustic scrubbers, biofilters, mist collectors and oxidizers are used for these systems. Carbon filters use activated carbon for air purification in waste management applications like keeping sewage systems cleaner. They have porous and absorbent granules which trap odors and chemicals in air flow. Caustic scrubbers and bioscrubbers are used in waste-water treatment plants to remove odorous gasses by biotrickling filter technology. In workplaces that have unpleasant odors caused by welding, plastic processing, high speed machining with coolants, tempering and quenching, mist collectors remove odors from gas streams. In order to manage smoke and exhaust odors, thermal oxidizers use chemicals that incinerate pollution in the air. Biofilters are small and fit inside pipes or tubes and remove sewer gas odors before the contents come in contact with humans.
