In continual process to treat effluent wash water, in a first stage a foam-building reactant is admixed to the water with air in a rotating perforated drum. The reactant forms bubbles in water containing ionized radicals introduced from subsequent stages. Foam is skimmed off and the water ionized, driving sedimentation. Sludge is then physically removed from the first-stage treated water and the foam-treated water. Foam generation and removal, oxidation, ionization and collection of treated water takes place in a vertical gravity-driven sequence within the same assembly. Gases liberated with radicals by the ionization process are returned to the foam generation reaction stage and are recycled within a closed system. Also claimed is a commensurate assembly with a pre-cleaning tank (10) into which foam generating agent is admixed and the pH is regulated (13, 14). The assembly has a main treatment block (20) with vertically stacked drum station (21), foam generation station (23), ionization station (24), clean water tank (25), sludge separator (30) and sumps (11, 26). The assembly further has a filter (40) and a clean water discharge (43).
