Abstract:

In a reverse osmosis fluid purification system, an input fluid is received at an input of the purification system, and a fluid purification run cycle is performed on the input fluid. The fluid purification cycle includes pumping the input fluid through a membrane with a pump at a first pressure and first flow rate to generate product fluid and waste fluid. The product fluid is provided to an external system and the waste fluid is provided to a drain port. The membrane is then rinsed after performing the fluid purification run cycle by providing the input fluid to the pump and pumping the input fluid through the membrane at a second pressure less than the first pressure and a second flow rate greater than the first flow rate for a predetermined period of time.
