ABSTRACT:
Treatment of sewage solids, sand, rubbish and the like, especially for the dumping and/or incineration with a reduced pollutant and moisture content, or similar disposal with the mechanical separation of the solids from a solid-liquid mixture, in which, to obtain the best possible dumping and incineration properties according to moisture and pollutant content, there is a vortex device with the aid of which organic substances adhering to the solids are dissolved and removed with the liquid, preferably to a further biological waste water treatment system, where the treatment of dirty waste water is concerned; in a similar manner, sand, rubbish and similar substances are treated even if they do not form part of waste water.
