The Universal Device for Sewage Purification with Closed System of Water Rotation
One of the basic sources of wildlife pollution by heavy metals is sewage from enterprises of mining industry, ferrous and nonferrous metallurgy and engineering industry. The problem of ensuring high-quality sewage treatment should be solved not only due to increase of purification degree but also by achievement of universality, reliability and ecological safety of technological process, as well as possibility of its maximal and even full automation. Therefore, from the standpoint of constantly becoming tougher norms of heavy metals contents in purified sewage, the most perspective way is creation of the closed system of a water rotation.
