Abstract

In the process, the waste water is cleaned by, before an aerobic biological treatment, carrying out a physico-chemical pretreatment, the impurities being floated using finely disperse gas bubbles and then skimmed off. The excess sludge from the aerobic biological treatment is fed back into the physico-chemical treatment stage. The resulting floated layer to be discharged from this physico-chemical treatment stage forms the only separation product.
