Watts Pure Water Series PWR4021 reverse osmosis systems are designed for commercial applications, providing flow rates of up to 10,800 gallons per day (40,878 liters per day). These high-pressure units effectively reduce total dissolved solids in water, utilizing high-pressure/high-rejection membranes that achieve a minimum average NaCl ionic rejection of 95 percent. The systems are intended for floor mount installation and include features such as a digital microprocessor-based controller, membrane auto flush, and various pressure gauges for monitoring system performance. The PWR4021 series is equipped with a robust support frame, fiberglass reinforced plastic membrane housings, and a comprehensive set of flow meters for permeate, reject, and reject recycle water. Additional features include a low feed water pressure safety switch, conductivity meter with alarm output, and inputs for tank level and pretreatment interlock. The systems require a minimum feed water pressure of 20 psi and are designed to operate within specific feed water guidelines, including pH levels between 6 and 9 and a maximum hardness of less than 1 grain per gallon. These reverse osmosis systems are suitable for a variety of applications, including municipal water treatment, laboratory use, and food processing, making them a versatile choice for engineers seeking reliable water purification solutions.
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
