SYSTEM FOR WATER TREATMENT AND SUPPLYING OF NUTRITIVE MIXTURE INTO SOIL IN THE PROCESS OF DROP IRRIGATION Russian patent published in 2004 - IPC

FIELD: agriculture, in particular, drop irrigation of farm crops, gardens, vineyards and other plantations. SUBSTANCE: system has pump station, nutritive solution tank, filter, pressure gauges, locking fittings, main pipeline, network of distribution pipelines and irrigation pipelines fitted with drippers. Filter is made in the form of horizontally mounted vessel having diameter and length ratio of 1:(1.3-10). Vessel is equipped with drain pipes, which are made from corrosion-resistant material and mounted in tiers. Surfaces of lower tier drain pipes are covered with filtering material. Pipes are arranged in vessel bottom part under layer of inert filler. Filler grains are of 1-5 mm size. Outer branch pipe of upper tier drain pipes is hydraulically communicated with high-pressure hydraulic cyclone. Hydraulic cyclone is equipped with sludge collector and sludge discharge valve, which are arranged in hydraulic cyclone bottom part. Netted screen is positioned in hydraulic cyclone cavity. Ends of lower tier drain pipes are connected through collector with water treatment fine filter. EFFECT: simplified construction, enhanced reliability in operation of water treatment system and increased water treatment extent. 1 dwg
