Description
Summary:Various aspects of the electroflotation technology for wastewater treatment and the extraction of valuable compounds from technological solutions have been reviewed. A brief description of the history of the appearance and improvement of the technologies based on the use of electroflotation process has been given. Their main operational parameters have been considered. Data on the mathematical simulation of the process have been provided. Achievements on the extraction of nonferrous and rare-earth metals from wastewaters, technological solutions, and technogenic waste have been discussed in detail. The results of investigations on the effect of various flocculants and surface-active compounds on the electroflotation process have been presented.
