Watts Commercial Reverse Osmosis Systems Up to 10,800 Gallons Per Day 7100073

Flow Rates: Up to 10,800 gallons per day (40,878 lpd) Series PWR4021 Reverse Osmosis (RO) Systems are commercial grade high-pressure RO units for the reduction of total dissolved solids from water. They are designed to supply reverse osmosis quality water with production rates ranging from 3,600 to 10,800 gallons per day. These units are designed for floor mount installations. Reverse osmosis is a process where high-pressure feed water is fed into a semi-permeable membrane. In the membrane, pure water is allowed to pass through the membrane material and exit as purified permeate water. Dissolved mineral salts are not allowed to pass through the membrane and become a concentrated reject stream that is sent to drain. These RO systems use high-pressure/high-r ejection membranes to achieve a minimum average NaCl ionic rejection of 95 percent.
