Watts Pure Water Series PWR2511 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 pro-
duction rates ranging from 150 to 1,200 gallons per day. The
standard units are designed for wall mounting. Where floor
mounting is preferred, the optional floor mounting kit Model
No. PWR2864 can be specified. 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-rejection mem-
branes to achieve a minimum average NaCl ionic rejection of
95 percent.
Watts Pure Water Series PWR2511 RO systems are a well
designed, rugged line of purifiers. This series comes with a
pre-selected assortment of features for monitoring and opera-
tion. Stainless steel membrane housings, inlet and outlet pre-
filter pressure gauges, low-pressure switch with delayed auto
restart, permeate pressure switch, adjustable reject recycle,
permeate and reject water flow meters, permeate water check
valve, inlet solenoid valve, membrane feed water pressure
gauge, adjustable reject valve, and membrane auto flush are
all standard features. The standard systems are designed to
feed an atmospheric storage tank or a pressurized bladder
tank. Reverse osmosis water has a wide variety of applica-
tions 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.
