Scrubber Systems operate at typical particulate collection efficiencies of 97% to 98% with emissions ranging from 0.1 to 0.3 kg/metric ton of phosphoric anhydride. Scrubber systems of varying types are used to dispose of the unused gaseous effluent. These systems also remove a portion of the SO2 emissions. Scrubber systems are fabricated entirely from FRP with the exception of recirculating pumps and spray nozzles, which are normally PVC.

Scrubbing system is an air pollution control device, which is used to remove particulates and/or gases from industrial exhaust streams. The term scrubber has referred to pollution control devices that used liquid to scrub unwanted pollutants from a gas stream. The term scrubb also used to describe systems that inject a dry reagent or slurry into a dirty exhaust stream to scrub out acid gases. Scrubbers are one of the primary devices that control gaseous emissions, especially acid gases.
