Process for the treatment of industrial water systems characterized by the following process steps: A: c. an inorganic alkali metal salt Me-X dissolved in water, where Me = NH 4 , and / or Na, and / or K and X = Br, Cl, SO 4 , NO 3 in amounts of from 0.01 to 30, preferably 5 -20% by weight and d. a non-oxidizing biocide in amounts of 10-50, preferably 20-30 wt .-%, are mixed together, the ratio of component b. to a. is between 0.1 to 40, preferably between 5 to 30 moves and the ratio of component a. to component b. is between 0.1 to 50, preferably 5 to 30 moves. B: this aqueous solution of components a. and b. and the oxidizing agent, component c, are metered separately in amounts of 10-40, preferably 20-30% by weight directly to the water system to be treated, the ratio of components (a and b) to component c being from 0, 5 to 2, ... |
