Series PWR8024
Commercial Reverse Osmosis
Systems
Flow Rates: Up to 100 gpm (378 lpm)
Watts Pure Water Series PWR8024 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 40 to 100
gallons per minute (151 to 379 lpm). 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 a drain. These RO systems use high-pressure/
high-rejection membranes to achieve a minimum average NaCl ionic
rejection of 99 percent.
Watts Pure Water Series PWR8024 RO systems are a well designed,
rugged line of purifiers. This series comes with a pre-selected assort-
ment of features, including our digital controller, for monitoring and
operation. Corrosion resistant fiberglass reinforced plastic (FRP) mem-
brane housings, inlet and outlet pre-filter pressure gauges, 316 stain-
less steel membrane feed water piping, low-pressure switch with pro-
grammable delayed auto restart, inputs for tank level and pretreatment
interlock, conductivity meter with percent ionic rejection displayed,
high-conductivity alarm output, adjustable reject recycle, permeate and
reject water flow meters, reject recycle flow meter, permeate water
check valve, inlet diaphragm valve, membrane feed and reject water
pressure gauges, programmable auto flush, and adjustable reject valve
are all standard features.
These systems are designed to feed an atmospheric storage tank for
collection of the reverse osmosis water. Reverse osmosis water has
a wide variety of applications including municipal water treatment,
steam boiler and steam sterilizer make up, laboratory use, spot free
rinsing, ice and beverage water, water for cooking, food processing,
metal plating and finishing, as well as water for humidification. Reverse
osmosis is also the pretreatment of choice for ion exchange type de-
ionization (DI) systems. Using RO water as make up to a DI system
reduces the exhaustion rate of the DI resin by up to 95 percent saving
time, money, and chemicals associated with DI resin regeneration.
