SYSTEM OF PRODUCTION OF PURE AND ULTRAPURE WATER Russian patent published in 2018 - IPC C02F9/12 C02F1/28 C02F1/32 C02F1/42 C02F103/04 C02F1/44 

FIELD: water and air purification technology.

SUBSTANCE: invention relates to water treatment. System for obtaining pure and ultrapure water includes a module for preliminary water preparation, module for obtaining water of type 3, module for obtaining water of type 2 and module for obtaining water of type 1. Water pretreatment module comprises a cartridge with prefilter 2, a cartridge with combined three-layer filter 3 consisting of activated carbon (I), a filtering filler KDF 55 (II) and a catalytic granular activated carbon (III), cartridge 4 with granular activated carbon from coconut shell (IV), low pressure sensors 6 and tap water quality 8, valves and connecting tubes. Type 3 water receiving module includes liquid pump 7, expansion vessel 10 with an upper level sensor and check valve 11, four cartridges with highly selective membrane filters of reverse osmosis 12, 13, 16, 17, water quality sensor 3 of type 20, valves, water outlet 3 of type 22, connecting tubes. Type 2 water receiving module includes storage tank 25 with integrated level sensors 29, 30, sterilizing capsule (31), which is a fluoroplastic membrane with pores of 0.2 mcm, filter 32 filled with soda lime, liquid pump 33, combined cartridge 34 consisting of a filter cake KDF 55 (II), catalytic granular activated carbon (III) and granular activated carbon from coconut shell (IV), a combined cartridge 35 filled with an ion-exchange resin of mixed type, an electromagnetic valve 36 with a water outlet 2 of type 37. Type 1 water receiving module includes UV sterilizer 38, type 1 water quality sensor, electromagnetic valves, microfiltration capsule 51, water output 1 of type 52, the connecting tubes, the combination cartridge 44 consisting of the catalytic granular activated carbon (III), the ultrafine metal-affinity sorbent (VI) based on the metal oxides and the ion-exchange resin (V) of the mixed type, combined cartridge 45 consisting of an ultradisperse metal-affinity sorbent based on metal oxides (VI) and an ion-exchange resin of mixed type (V), ultrafiltration membrane 48, a feedback channel.

EFFECT: invention makes it possible to create a system for obtaining pure and ultrapure water from tap water without first preparing it and changes in individual components of the system to expand the list of substances removed from water and increase the cleaning efficiency without additional energy inputs.
