Designing facilities for the treatment of industrial storm water of steelworks
Summary
In line with the environmental program being developed over many years to reduce the negative impact on water resources, the steelworks launched modern facilities for the treatment of industrial storm water of a complex composition. The greatest difficulties are associated with the presence of oil products and heavy metals in industrial storm water provided that the requirements for the removal of heavy metals are very stringent, primarily regarding the copper concentration, i.e. it should not exceed 0.001 mg/dm3 in the effluent. To estimate the efficiency of the existing treatment facilities and take measures for their upgrade, the experts of the steelworks carried out some research work to select the optimal equipment and technological treatment scheme. After the pilot tests, the previously proposed schemes were rejected and a new one was developed that should meet all the requirements. The newly designed facilities were put into constant operation with the required treatment efficiency achieved. For the first time a dynamic softening system (DSS) with columns 1800 mm in diameter was used on an industrial scale to remove heavy metals from wastewater.
