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, 2000 ppm TDS, and pH 7 with a feed pressure of 225 psi. Individual mem-
brane productivity may vary (± 15%). May be operated on other feed waters with
reduced capacity.
* Percent rejection is based on membrane manufacturer’s specifications; overall sys-
tem percent rejection may be less.
Specifications
Watts Pure Water Series PWR8024 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 membranes.
A 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 backwashing sediment filter shall
also be installed on the RO feed water line to reduce the silt density
index of the water to prevent particulate fouling of the RO membranes.
The RO system shall be a high-pressure/high-rejection type unit com-
plete with 316 stainless steel pre-filter housing and high-pressure
membrane feed water piping, permeate and reject water flow meters,
reject recycle water flow meter, pre-filter inlet and outlet pressure gaug-
es, pump discharge pressure gauge, membrane feed and reject water
pressure gauges, FRP membrane housings, automatic inlet diaphragm
valve, low feed water pressure switch, reject and recycle valves, digital
controller with conductivity meter and high-conductivity alarm output,
percent ionic rejection displayed, storage tank level and pretreatment
interlock inputs, multistage 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
atmospheric 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 require-
ments are 480 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 - 38°C).
The system shall produce reverse osmosis quality water with 99 per-
cent minimum average ionic rejection of total dissolved solids when
operated within the manufacturer’s operational specifications.
