Sludge, even if it is thickened, still has high moisture content up to%. Dewatering efficiency of a specific method or technology could be described by the TS content in the sludge layer, which depends on the water type in the sludge. The water in the sludge may appear in four types (Vesilind and Hsu, 1997; Kopp and Dichti, 2001): 1.

Aug 28, 2020 · The free water content of the sludge conditioned by HACPAeased by 9.26%, 15.43% and 28.24%, respectively, compared with that of the sludge conditioned by CPAM, which is because the copolymer HACPAM contains more hydrophobic groups for promoting the conversion of bound water in sludge flocs into free water.
