Specifications
Watts Pure Water Series PWR4024 reverse osmosis system shall
be installed to provide reverse osmosis quality water. The RO
system shall be installed after a Series PWS water softener so that
scale forming calcium and magnesium hardness cannot scale the
RO membrane. Series PWC backwashing carbon filter shall be
installed on the RO feed water line to remove chlorine and prevent
membrane degradation due to chlorine attack. Series PWM back-
washing sediment filter shall also be installed on the RO feed water
line to reduce the silt density index of the water to prevent particu-
late fouling of the RO membrane.
The RO system shall be a high-pressure/high-rejection type unit
complete with permeate and reject water flow meters, reject recy-
cle water flow meter, pre-filter inlet and outlet pressure gauges,
membrane feed and reject water pressure gauges, FRP mem-
brane housings, automatic inlet diaphragm valve, low feed water
pressure switch, reject and recycle valves, digital controller with
conductivity meter and high-conductivity alarm output, storage
tank level and pretreatment interlock inputs, 10 horse power mul-
tistage centrifugal high-pressure pump, and all other components
necessary for proper operation. The system shall be a floor mount
design. The RO permeate water shall be collected in an atmo-
spheric storage tank with the tank level controlled by an electronic
level float. The RO shall be equipped with inputs for the tank level
float as well as pretreatment interlock to shut the RO system down
in the event the pretreatment begins a backwash cycle. Electrical
requirements are 230 volt 60 hertz three phase. A local drain is
required to accept drain water from the system. The feed water
pressure must not fall below 20psi. The feed water temperature
must not fall below 35°F or exceed 100°F (2-39°C).
The system shall produce reverse osmosis quality water with 97
percent minimum average ionic rejection of total dissolved solids
when operated within the manufacturer’s operational specifications.
Feed Water Guidelines

CaCO3 (Softened) or anti scale
chemical injection if not softened
(contact your Watts representative)

Notes:
* For all other guideline information please contact your Watts representative.
* Published maximum production rates are based on a feed water of 77°F, SDI
of less than 3, 1000 ppm TDS, and pH 8. Individual membrane productivity may
vary (± 15%). May be operated on other feed waters with reduced capacity.
* Percent rejection is based on membrane manufacturer’s specifications; overall
system percent rejection may be less.
