Local Treatment of Industrial Wastewater of the Samara Tank Factory Before Discharge into City Sewerage

Summary

A flow chart of local treatment of wash water of a hot metal galvanizing line making it possible to reuse them in production is proposed. It is established that in the course of waste water treatment according to the flow chart proposed the salt content in wash water does not increase and the total volume of water consumption and wastewater disposal of the factory is reduced. A possibility of using the filter-press for water clarification at reagent treatment is proved. The technology of reverse osmosis is used for organization of recirculating water supply.

Key words
