Abstract: A method of treating cooling circuit water of industrial plants (2) contaminated with organic substances and inorganic particles, comprises the following steps: a) separating the organic substances and inorganic particles from the cooling circuit water to obtain precleaned cooling circuit water; b) cooling the precleaned cooling circuit water by an open cooling tower (11) to obtain cooled precleaned cooling circuit water; c) desalinating at least a partial volume flow of the cooled precleaned cooling circuit water by an desalination plant (14) to obtain cleaned cooling circuit water; and d) adding bacteria capable of degrading organic substances present in the cooling circuit water. The bacteria are added to the cooling circuit water before the separation in accordance with step a), before the cooling in accordance with step b) and/or before the desalination in accordance with step c), to form a biological cleaning stage.
