Abstract
1438719 Flocculating sewage sludges CALGON CORP 28 Aug 1973 [1 Sept 1972] 40394/73 Heading C1C [Also in Division C3] Solids suspended in water (e.g. sewage sludges) may be flocculated by adding to the water 0À1 to 20 p.p.m. of a cationic water soluble copolymer of a cationic monomer and a watersoluble polyunsaturated monomer. The cationic monomer may have the general formula in which R 1 is H or CH 3 ; R 2 is H or C 1-4 alkyl; each of R 3 and R 4 is H, C 1-12 alkyl, benzyl, or hydroxyethyl, or R 3 and R 4 together with the nitrogen atom to which they are both attached, form a cyclic ring containing one or more hetero atoms; Z is the conjugate base of an acid with a dissociation constant greater than 10
