Liquid filters are mechanisms that are used to remove
impurities that occur in liquids both from natural and unnatural sources.
In order to achieve the filtration process, a liquid is passed through
a permeable or porous substance that lets the liquid pass through while
catching the larger solid particles that need to be removed. For the
liquid to flow there must be a pressure difference that causes it to
move through the filter. Usually, liquid filters are used to clean or
purify a product or extend the life of piping by removing corrosive materials
that induce erosion. Liquid filters have also been used to remove bacteria
from certain liquids to prevent spoiling and, in other cases, to remove
harmful particles so that the liquid may be recycled and reused.
Water filters are the most common type of liquid filters. They use semi-permeable
filtering elements that allow water molecules to pass through the liquid
filters, while hindering water soluble elements such as lead, chlorine
and salt, among others. Carbon is the most popular type of liquid filter
element that is used in water filters. It has a very good performance
record for removing most water soluble imperfections. Water filters are
popular for personal home purification purposes because removing unwanted
sediment matter results in higher quality, better tasting water.
Liquid filter manufacturers offer various types of products to serve
particular purposes. For instance, high-flow filtration systems are used
for situations that have a high amount of particulate, water count or
acid, while low-flow filtration systems are used for the opposite reasons.
Bearing filtration systems are able to keep the filtered lubrication
oil clean and, in effect, extend the life and effectiveness of the oil,
while maximizing its performance. Additionally, vacuum dehydration systems
use vacuums to move liquid through the liquid filters at a high flow
rate. Liquid filter manufacturers use various types of membranes in their
products, which also vary greatly by application. A microfiber is able
to provide a high retention of small particles, similar to felt, which
is good at removing particles of many different shapes and sizes. Multi-filament
mesh is an inexpensive woven substance that is very good for sifting
coarse particles.
Many factories are required to utilize liquid filter manufacturers to
keep waste water within federal guidelines. Some industries that use
liquid filters include textile mills, cosmetics, food and beverage, electronic
components, tool manufacturers, ship builders, pulp and paper mills,
foundries, air conditioning and oil and gas wells. Picking the liquid
filters with the correct amount of permeability is critical. How permeable
the filter media is determines what size particles are able to make their
way through the filter downstream. Different permeabilites result in
varying flow rates. Picking the correct filtration system can mean choosing
between a higher rate but less filtered unit and vice versa. Other important
considerations include whether the filtration system will impact productivity
in a negative way and if the short- and long-term associated costs are
reasonable.
Types of Liquid Filters
- are receptacles that liquid is passed through to remove impurities.
-
are filters that contain carbon in their solid state. They use absorption
to remove unwanted soluble substances from water and can be found in
many applications, including personal water filters and purifiers.
- have a receptacle that holds the filter media.
- are used to remove chemicals with a carbon filter.
- is the material through which liquid is passed to remove all particles and impurities.
-
are designed to filter sediments from fuel supplies because particulates
are harmful to engines and can significantly decrease engine life.
- remove impurities from water in industrial settings.
- consist of a number of uniform
folds and generally have a geometric shape, such as a cone, cylinder,
plate or others.
-
are filter elements used in reverse osmosis applications. Reverse osmosis
is a process that uses pressure to move water molecules through a membrane;
the impurities that remain behind are then discharged in a waste stream.
- are used in filtration systems to remove large particles.
-
have both inlet and outlet ports situated at one end. The ports of their
major axes are in a straight line with the axis of the filter element
perpendicular to the line.
-
are complete units that begin with a "dirty" water source
and result in a purified end product. In the system, unpurified water
is filtered and then acquired as a "clean" product.
-
have filter elements that are designed to filter particle matter from
both air and water. They can be found in wet/dry vacuum cleaners and
fish aquariums.
Liquid Filters Terms
- The diameter of the largest spherical particle that
is able to pass through a filter in certain testing conditions. The AFR
indicates the biggest opening in any given filter element.
-
A process by which a solid is employed in the removal of a soluble substance
from water.
- The
number of similar-sized particles moving upstream through a filter in
a ratio to the number of particles moving downstream.
- A condition
in which particles fill and block the entire area between adjacent sections
of a filter.
-
The gas pressure at which a constant stream of gas bubbles is released
from a wet filter element under specified testing conditions.
- A mechanism that ensures proper fluid flow when pre-selected
flow levels are surpassed. The valve allows for part or all of the fluid
to bypass the filter.
- The
tendency of contaminating particles to pass through a low-density area
of a poor filter around its seal points.
-
The filtering of liquids that have only a small amount of solid particles.
-
Maximum pressure a filter element can withstand without any permanent
deformation(s).
- The amount of time that a filter is able to operate effectively
before it needs to be cleaned or replaced.
- Difference in pressure between any two positions of a component
or system.
-
Area of the filter element that is exposed to fluid flow.
- Ability
of a filter element to remove a particular contaminant at a specified
contaminant concentration. Efficiency is typically expressed as a percentage.
- The porous material that performs the actual filtration process.
- An enclosure
that directs the fluid flow through the filter element.
- The average size of the pores of a given filter media.
-
The release into the flowing fluid of components that make up the filter
media.
- A small
opening in a filter that allows fluid to pass.
- Optimal
flow for which a certain filter is designed.
- Collection and settling of micro-sized particles
inside a fluid system.
