WATER FILTRATION SYSTEM Russian patent published in 2019 - IPC C02F1/00 B01D27/00 B01D29/00 C02F103/04 A47J31/46 

FIELD: water purification.

SUBSTANCE: invention can be used to purify water. Water filtration system (100) comprises filtering cartridge unit (10), water intake pipe (20), purified water pipeline (30), clean water pipeline (40) and waste water discharge pipeline (50). Filtering cartridge unit (10) has water inlet (110), purified water discharge (120), purified water return hole (130), clean water outlet (140) and waste water discharge hole (150). Clean water pipeline (40) is communicated with clean water outlet (140) and has clean water outlet hole (410) and second valve (420) configured to control clean water pipeline (40) blocking and unblocking. Pipeline for discharge of waste water (50) has a first end communicated with outlet hole for waste water (150), and a second end communicated with environment. Filtration system (100) is configured to unblock the purified water pipeline (30) and to block the clean water pipeline (40) when producing purified water, and in production of pure water with possibility of unblocking of treated water pipelines (30), clean water (40) and discharge of waste water (50).

EFFECT: invention ensures compactness of the water filtration system and reduces the number of pipelines.
