QOG420 - Flow restrictor
Flow limiter (for the waste water) with flow rate of 420 cc/min. Used in reverse osmosis systems, at the outlet of dirty water to the drain.
Correct and long-term work of osmotic membrane is determinated by the flow of flow limiter. Flow rate forced by flow limiter determines the rinsing of the membrane, which means collecting of accumulated contaminants and rinsing them out into drains.
The limiter is matched to the membrane with a efficiency of 75 GPD (280 L/24h). When flow limiter is working on very polluted water it should be changed every few years.
