Electroplating wastewater treatment technology with modified aluminosilicate adsorbent

The article is devoted to the creation of a technology for the treatment of galvanic effluents containing heavy metal ions (ITM) and acid-base effluents using a modified aluminosilicate sorbent. The results of theoretical and experimental studies of the technology of wastewater treatment from ITM, using filtration on short layers of modified aluminosilicate sorbent, are presented. Dolomite and magnetite are selected as modifiers. The physicochemical mechanism of sorption treatment of wastewater with a modified adsorbent is substantiated. When using the proposed technology of wastewater treatment, their preliminary reagent treatment and division into streams are excluded. The high quality of purified water with a modified adsorbent makes it possible to use it in closed water use systems. A method for activating the adsorbent is proposed.
