Activity of many industrial enterprises is accompanied with considerable amount of liquid technogenic waste products containing toxic heavy and non-ferrous metal ions as well as petroleum products, oils, and surfactants that are discharged to surface water together with waste water and used technical solutions. Therefore, efficient wastewater treatment is one of the main directions to decrease the industrial negative impact on the environment. The main sour?es of wastewater pollution with heavy and non-ferrous met...

The present study has been dedicated on the removal process of heavy metal ions from electrolyte solutions by using methods of electroflotation and subsequent filtration in a multi-component system with the presence of various surfactants of different nature. The research was conducted in a five-component system comprising ions of iron (II), nickel (II), copper (II), plumbum (II), and zinc (II) (the total concentration of metal ions is 200 mg/l). The research was conducted in a highly concentrated electrolyte solu...
