Abstract

Advanced water supply systems for industrial enterprises represent complex facilities that include the supply of fresh water and its preparation for the process, treatment, decontamination and disposal of waste water, disposal of the resulting residue, and often the organization of a closed water cycle. Designing and operating such facilities is a complex technical and environmental task, which must be solved using the best available technologies. The management system for the drainage waters generated in diamond mining at the Lomonosov GOK of PJSC Severalmaz in the Arkhangelsk Region is a typical example. The precipitation indicators for the suspension in the drainage water were established using the traditional coagulants of aluminum sulfate and hydroxochloride, as well as an experimental sample of a calcium-aluminosilicate inorganic precipitator. The results of experiments with different coagulant dosages were used to establish the average and effective precipitation rate, the residual aluminum content in the water, acidity and turbidity of the clarified drainage water.
The results obtained allow substantiating the higher efficiency of the experimental coagulant in terms of the water clarification rate and the possibility of meeting the sanitary standards for water discharge into natural water bodies envisaged by SanPiN 2.1.5.980-00.

The work was carried out with the financial support of the Russian Science Foundation under Agreement No. 18-19-00577 dated April 26, 2018, on the provision of a grant for fundamental and exploratory research.
