The current work is devoted to development and improvement of integrated water treatment technologies, which provide both high efficiency removal of contaminants with small level of resource consumption. The influence of air flow on the process of ferrite treatment for concentrated zinc-containing wastewater of galvanic facilities has been investigated. The dependence of the efficiency of heavy metal ions extraction on aeration rate was determined. The most effective results of wastewater treatment are achieved at small values of aeration rate. The efficiency of removal for ferrum ion has reverse dependence and increases with growing of air flow. The influence of the oxidant amount on the structure of sediments after ferritinization treatment has been studied. The sediments are chemically stable, have a dense crystalline structure and ferromagnetic properties. On the basis of experimental researches, the best aeration rate for the ferritization process has been determined, which allows to rational use of electric energy in  the technological scheme of ferrstization process. The directions of further researches for wastewater treatment of zinc galvanic lines are to achieve of maintenance for all necessary parameters of water quality for closed circuit water supply systems.
