Abstract

1489046 Dewatering sludges CALGON CORP 13 Feb 1976 5825/76 Heading ClC [Also in Divisions C3 D2 and El] In an otherwise conventional process for dewatering an aqueous waste sludge by chemical conditioning followed by mechanical dewatering, there is used as the conditioning agent an anionic or cationic derivative of an amide polymer which has been produced by modifying the polymer by reaction in an inverse emulsion (see Division C3). The polymer may be aminomethylated and optionally quaternized, or may be sulphomethylated. Example 14 illustrates sludge dewatering, the polymer used being the product obtained by aminomethylating polyacrylamide with a formaldehyde/dimethylamine adduct.
