Abstract

Effluent is continuously purified by (1) first combining (a) effluent of pH 4-11, opt. already subjected to pri. treatment to remove solids, with (b) activated sludge, to produce a mixture contg. 300-15,000 ppm solids, then (2) agitating the mixture and adding a gas contg. O2 and (3) removing mixture from treatment vessel and separating the solids from the supernatant water. 5-1500ppm of activated C or 25-2500 pp, Fuller's earth (w.r.t. feed effluent) is added, having a specific surface >=100m2/g and particle size passing a sieve with 200 meshes per inch.
