Essay: "Good Chemistry," M. Hubbe, Oct. 2001 - NCSU

Chemicals coagulants such as poly-aluminum chloride (PAC), essentially the same coagulants used in paper formation, can be used to assist pressing more water from sludge (Ghosh et al. 1985; Leitz 1993; Pawlowska, Proverb 1996). Side benefits of sludge dewatering may include a) more stable, solid-like sludge, b) the colloidal materials in the ...
