FIELD: filters for purification of liquids from suspended substances. ^ SUBSTANCE: the invention presents a filter intended for purification of liquids from suspended substances, coloration, turbidity, ions of heavy metals, an ammonium, oil products. The filter may be also used at the solution of problems of preservation of the environment. The filter for purification of liquids contains a housing, branch-pipes for delivery and withdrawal of liquids, branch-pipes for feeding of regeneration solutions, the fixed partitions executed from geotextiles with density of 50-150 kg / m3 and a located between them layer of a sorption-filtration material made on a base of granulouse zeolite with fineness of granules of 2-4 mm. In the capacity of the regeneration solution they use sodium chloride with concentration of 2-10 %. The filter ensures high efficiency of purification of a liquid, has a simple design and capability to work in purification and regeneration modes. ^ EFFECT: the invention ensures high efficiency of purification of liquids, has a simple design and purification and regeneration modes of operation. ^ 1 dwg |
