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 pro-
ductivity 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.
Specifications
Watts Pure Water Series PWR4022 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. Series PWC backwashing carbon fil-
ter shall be installed on the RO feed water line to remove chlo-
rine 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 complete with permeate and reject water flow meters,
reject recycle water flow meter, pre-filter inlet and outlet pres-
sure gauges, membrane feed and reject water pressure gaug-
es, FRP membrane housings, automatic inlet solenoid 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, 7.5 horse power multistage centrifugal high pressure
pump, and all other components necessary for proper opera-
tion. The system shall be a floor mount design. The RO perme-
ate 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
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 tempera-
ture must not fall below 35°F or exceed 100°F (2 - 38°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.
