WATER TREATMENT DEVICE Russian patent published in 2016 - IPC C02F1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to combined devices for separation of inhomogeneous liquid media and can be used in agricultural land reclamation, particularly in drip irrigation systems, micro-irrigation and sprinkling, as well as during water purification or water treatment. Water treatment device comprises a hydraulic cyclone with a pipe filter mounted inside a drain pipe, a sludge accumulation tank and pipeline manifold to periodically change mode of operation: filtering water suspension and flushing pipe filter with reverse current. Pipe filter comprises outer and inner layers of mesh, to form cells, bearing frame with placement on its inner cylindrical surfaces of at least two filter partitions, space between which is filled with filter glauconitic load. Outer and inner layers of bearing frame made of glass fibres, treated with epoxy compound. Filter partitions are made from smooth polymer monofilaments in form of a mesh with cell size 0.07-0.3×0.07-0.3.

EFFECT: technical result is improved reliability of pipe filter and longer operational life thereof, high degree of purification of aqueous suspension from finely dispersed suspensions, toxic impurities and dissolved salts, enrichment of irrigation water with macro- and micro-nutrients, necessary for maintenance of optimum food regimen of crops.
