APPARATUS FOR WATER TREATMENT Russian patent published in 1998 - IPC

FIELD: environmental control; water supply systems, in particular, for use in movable and stationary units for purifying and decontaminating natural, predominantly, drinking water. SUBSTANCE: water treatment apparatus comprises water supply line, water pretreatment assembly, sorption purification assembly and water discharge line for directing treated water to consumers. Water pretreatment assembly includes concentrate discharge line provided with throttling device. Apparatus further comprises decomposing reactor made in the form of air- and water-tight shell consisting of two chambers, namely: cavitation chamber housing ultrasonic oscillations generator, and photochemical chamber housing ultraviolet radiation source. Inlet of cavitation chamber is connected with outlet of water pretreatment assembly, while outlet of photochemical chamber is connected with inlet of sorption purification assembly. Water pretreatment assembly comprises single hollow-fiber untrafilter or series of in-parallel connected hollow-fiber ultrafilters. Sorption purification assembly comprises single sorption filter or series of in-parallel connected sorption filters. Optionally, apparatus may be provided with pump having filter for primary water purification, and four-way cock arranged at inlet of water pretreatment assembly. Filter for primary water purification is arranged in water supply line. Water can be treated to remove wider range of harmful substances, including dissolved organic matter, toxic and radioactive substances. EFFECT: higher degree of water decontamination from pathogenic microflora; increased apparatus service life. 3 cl, 1 dwg
