Document Type and Number:
WIPO Patent Application WO/2022/234738
Kind Code:
A1
Abstract:
Provided is a practical cycle filtration system. Raw water 11 stored in a raw water tank 10 circulates by passing from the raw water tank 10 through a flow channel pipe 31 to be purified by a reverse osmosis membrane water purification unit 51 located in the middle of the flow channel pipe 31, then flowing toward a tap 71 and out of the tap 71 to be received by a bowl 72, and thereafter returning to the raw water tank 10. On the other hand, the raw water 11 stored in the raw water tank 10 circulates through a second flow channel pipe 34, regardless of whether the tap 71 is opened or closed, by means of a second pump 23 that is periodically driven, and is repeatedly purified by an ultraviolet sterilization device 92 and an aeration device 93 located in the middle of the second flow channel pipe 34.
