Design and Applications of Physicochemical PAC Process Systems

Example 3 (Design and Applications of Physicochemical PAC Process Systems) 

Powdered activated carbon (PAC) is used in water and wastewater treatment facilities to adsorb soluble organic materials and to aid in the clarification process. PAC is fed to a treatment system using chemical feed equipment similar to those used for other chemicals that are purchased in dry form. The spent carbon is removed with the sludge and can then be discarded or regenerated. Regeneration can be accomplished in a furnace or wet air oxidation system. There are seven types of physicochemical PAC process systems (21-24,36,37,45,46,52)  

PAC sequencing batch reactor involving the use of gravity settling basins for clarification. 

Continuous physicochemical PAC process systems involving the use of dissolved air flotation (DAF) clarifiers for clarification.
