- Abstract
- On the basis of experimental researches the apparatus for purification industrial of waste waters from connections of non-ferrous metals by a complex method is designed: by a membrane electrolysis and electroflotation. Designed as a continuously-working electrolyser compromising membrane electrolysis and electroflotation in a single box-type structure. The apparatus can be used to removal cations of the metals Cu, Ni, Zn, Cd, Cr, Al, Sn and others, both individually and when in a mixture in the interval of initial concentrations 10-300 mg/l in the form of hydroxides. It also makes possible and recovery of up to 50 % of treated water for reuse in the production cycle.
