Method and apparatus to flush a reverse osmosis system

摘要

A home RO filtration system includes a membrane module (105) having an inlet (112) connected to a feed line (114), the membrane module also having a concentrate outlet (116) coupled to a concentrate line (115), and a permeate outlet (118) coupled to a permeate line (120). The permeate line (120) communicates with a faucet (122). The system includes a flush reservoir (130) communicatively coupled between the permeate line (120) and the feed line (114). The system is configured such that after the faucet (122) is turned off, a portion of permeate is delivered to the reservoir (130) and then delivered to the inlet (112) of the module (105) to flush the module (105).
