filtration technology, microbe reagent-free preparation of water for drinking from water reservoirs under conditions of its storage in underwater and surface long-distance vessels, for crews of spacecraft and orbital stations. SUBSTANCE: microfilter of water preparation system has body with branch pipes of water supply, discharge of purified water and suspensions, driving shaft with upper and lower discs, non-rigid filtration partition anchored between them. Lower disc is fitted with mechanical ultrasound radiator in the form of perforated ring interacting with supply chamber of compressed air which cover resting against ring of lower disc is perforated. Pressure space of upper disc carries blades, communicates with branch pipe supplying water and is equipped with perforated tubes mounted perpendicular to upper disc and communicating pressure space with internal space of non-rigid filtration partition. The latter is connected by collector to source of supplying electric current to its surface. Branch pipe supplying water into pressure space of upper disc communicates through disintegrator with biological filter that includes body with technological branch pipes forming sections together with granular immobilization packing placed on partitions. Tangential branch pipes feeding air from blower are located under partitions. EFFECT: enhanced efficiency of water preparation and expanded technological capabilities. 3 dwg
