Abstract

Procedure for the purification of water from cooling circuits in steel mills and steel mills, with a slag collector for the preliminary separation of coarse impurities, such as rolling scale and similar, and a device arranged downstream for the fine purification of wastewater such as cyclone separator, gravel filter with updrafts and the like, characterized in that for the wide separation of floating materials, especially oil, and for an increased separation of the slags before the fine purification, a or more times the direction of circulation of the cooling water inside the slag collector by means of deviations, because part of the previously purified wastewater is separated from the collector, mixed with compressed air and added to the raw water of the circuit before its introduction into the slag pan, feeding compressed air at the same time to the water of the slag picker.
