Abstract

The invention relates to a process for the treatment of polluted water, in particular process water or sewage in an at least partially closed circuit, preferably a closed circuit, and preferably for the paper industry. The charged water or sewage first undergoes primary cleaning (24, 42, 12a) to reduce the solid content to less than 200 mg/l, subsequently to set the pH of the sewage at a value of up to 6.5, and then to heat the primary cleaned water or sewage to a temperature of approximately 70 to 160 DEG C and to convey it to a reaction chamber (12b) in which oxidation takes place so that the pre-purified sewage subsequently flows against a diaphragm filter (reverse osmosis) (14) and/or a nanofilter, or receives further purification.
