ULTRAPURE WATER PRODUCTION SYSTEM Russian patent published in 2021 - IPC C02F9/12 C02F1/28 C02F1/32 C02F1/44 C02F103/04 

FIELD: water treatment.

SUBSTANCE: invention relates to the field of water treatment. The ultrapure water production system includes: pressure regulators (1, 16), a water pretreatment module (2) consisting of a mechanical cleaning filter, a combined filter with granular activated carbon and a KDF filter medium, a filter with a compressed carbon block; electromagnetic valves (3, 9, 18, 19, 30, 31), membrane pumps (4, 21), electrical conductivity sensors (5, 7), a membrane block (6), check valves (8, 17, 20), a storage tank (10), a filter for connecting the storage tank with the environment (11), a strain gauge platform (12), a temperature sensor (13), a pressure sensor (14), combined cartridges (22, 26) filled with activated carbon and ion-exchange resins of mixed type, a photocatalytic reactor (23), a membrane sterilizing finishing cleaning cartridge (27), a conductometric sensor (28), a flow sensor (29), a sampling point (34) of ultrapure water with a thread for fixing standard bottles (32), a sterilizing capsule (33) made of 0.2 mcm fluorine plastic to connect the bottle capacity with the environment.

EFFECT: obtaining ultrapure water with a reduced total organic carbon content of less than 0.5 mcg/l, preventing secondary contamination of water during its selection.
