Аннотация: The organization of a closed cycle of water use is one of the priorities for both recycling water supply systems and wastewater treatment systems of industrial enterprises. Water cooling systems are considered and the possibility of closed water cycle organization is estimated. For cooling systems of circulating water supply of industrial enterprises, depending on the water content, the cooling scheme can be: running, open (evaporative cooling) and close. The technological scheme of water treatment based on the complex approach is offered. This approach allows to create a closed cycle of water use with high quality of purified water and allows the use of ferrous sediment. Water-treatment technologies are considered. Membranes are used at 2 stages of aeration process: * directly at the stage of aeration: it is possible to obtain air bubbles of 350 - 450 micrometers with the help of ceramic membranes; * at the last stage of filtration: in addition to the removal of iron, the content of manganese, microorganisms in the water is reduced, the content of chlorine and heavy metals is reduced. Also produced partial softening of water, while maintaining 80-110 mg / l of salts necessary for the human body. The water is transparent and increase its flavor. Iron-containing slurries can be used as additives to raw materials for the production of cement clinker. The inclusion of small amounts of these additives in the raw material mixtures for the production of cement clinker essentially does not change the firing technologies used in cement enterprises and does not affect the quality of the clinker produced. Also, iron-containing slurries can be used in the ingredients of various functional purposes: fillers, promoters of adhesion of rubber to metals, vulcanization activators The conducted research on the study of bubbling showed the effectiveness of the use of ceramic tubular membranes as a dispersing material. This technical solution allows: * Reduce water intake and related charges by 5-10%; * Create a closed circuit with no liquid waste and charges for their discharge into water bodies; * Reduce the amount of solid waste and dispose of it; * Reduce the need for production facilities; * To reduce operating costs for chemical reagents and replaceable elements; * Increase the capacity of the washing water recycling system due to the modularity of the equipment, without replacing the existing equipment.
