 These solids can be wasted and disposed of as a slurry, dewatered to a compact, stable cake, or pumped as a slurry to a wet air oxidation unit for further processing to regenerate the carbon and destroy the biological solids.The system as it exists today was developed in the 1970s under a collaborative effort between DuPont and Zimpro.PACT systems can be used to treat very difficult to treat wastewaters including
Powdered activated carbon is also used in the processing of drinking water at treatment facilities, primarily on a seasonal basis in order to deal with aesthetic problems with the water such as odor and taste issues associated with Geosmin and 2-MIB.
