Watts Pure Water Series PWR4024 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
20 to 30 gallons per minute. 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 mem-
brane 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 97 percent.
Watts Pure Water Series PWR4024 RO systems are a well
designed, rugged line of purifiers. This series comes with a pre-
selected assortment of features, including our digital controller for
monitoring and operation. Corrosion resistant fiberglass reinforced
plastic (FRP) membrane housings, inlet and outlet pre-filter pres-
sure gauges, low-pressure switch with delayed auto restart, inputs
for tank level and pretreatment interlock, conductivity meter, 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, 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 steril-
izer make up, laboratory use, spot free rinsing, ice and beverage
water, water for cooking, food processing, metal plating and finish-
ing, 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.
