Carbon Adsorption Scrubbers

Carbon Adsorption Environmental Scrubbers. These scrubbers perform in the same manner as those described above in General Environmental Scrubbers, except that activated carbon is the material used to remove gases and odors from the air stream. Carbon scrubbers are used where the concentration of volatiles are low, and the air volumes are relatively large. The gases are removed by adsorption, meaning the gas is gathered in a condensed layer on the surface of the carbon. The used carbon is usually contained or buried to prevent environmental contamination.

Things to Consider: Air flow range, Materials of construction, Height, Diameter, Carbon capacity, Inlet pipe diameter, Outlet pipe diameter, Adjustable inlet damper for air flow adjustment, Ease of carbon bed change out, Differential pressure gauge, Condensation drain, Stainless steel carbon bed grounding rod, Carbon support bed, Mounting tab provision, Stand alone or series/parallel capability, Pressure blower option, Control panel option, Skid option, Rain hat with bug/bird screen option, Dimensions, Weight, Warranty.

Oxidizer Scrubbers

Oxidizer Environmental Scrubbers. These scrubbers remove noxious odors. They are fixed-bed systems, containing two layers of oxidizing media and, sometimes, a layer of polishing media. There is usually one moving part, a blower. Foul air goes in, clean air comes out. There are no chemicals to add and there is no maintenance to do for the service life of the scrubber.

Things to Consider: Oxidizer type, Destruction efficiency/capability, Required airflow, Temperature range.

General Environmental Scrubbers

General Environmental Scrubbers. Scrubber systems are air pollution control devices that are used to remove particulates and gases from industrial exhaust streams. Scrubbers are classified as either wet or dry. Wet scrubbers use a liquid to scrub unwanted pollutants from a gas stream. Dry scrubbers inject a dry reagent or slurry into a dirty exhaust stream to scrub out acid gases. If there is no useful purpose for the scrubbed out solid waste, it is usually contained or buried to prevent environmental contamination.

Things to Consider: Scrubber fixed or portable, Orientation horizontal or vertical, Separation/filtration system, Airflow, Efficiency, Minimum particle size filtered, Continuous duty requirement, Need for HEPA/ULPA filters, Instrument panel requirement.
