Abstract

Raw water and sewage are purified using a cationic aminoplastic resin with a view to using them or releasing them into the environment. The resin, which is quaternized, preferably using dimethyl sulphate, is a product which is obtained by condensing an aldehyde and a nitrogen-containing compound. The aldehyde is glyoxal, where appropriate mixed with formaldehyde, and the nitrogen-containing compound is melamine, where appropriate having a low content of urea. The resins can be used in quantities of between 2 and 500 ppm, preferably between 4 and 20 ppm, for purifying raw water and between 30 and 300 ppm for purifying sewage.
