Water Requirements of Selected Industries

Rolling mills produce wastewater during the cooling of bearings and shafts. The water consumption is about 10 m 3 /ton, but by recirculation it is possible to reduce this amount of water by a factor of two to seven. Wastewater from the iron and steel industry can contain up to 5% of grease and oil when recirculation of the wastewater takes place.
