Improvement of Technological Modes of Electrodialysis Apparatus for Treatment of Chromium-Containing Waste Waters
Waste waters of galvanizing plants contain toxic heavy metals what causes pollution of the environment and endangers it. The present study aim includes concentration of chromium (VI) ions from chromium plating waste waters, purification of waste water and its reuse for development of waste-free tech...
