Note: Peak service flow rate is for intermittent use only and is not to be interpreted as continuous service flow rate capability. These
systems are designed to treat the domestic water used in a single family dwelling. For irrigation water treatment or higher volume
applications please contact your Watts representative.

PWBWIRON System Overview
PWBWIRON systems are selected for use when the concentra-
tion of iron, manganese, and hydrogen sulfide in water need to be
reduced. They use the model 2510 AIO Control Valve to reduce the
contaminants in the water without the use of chemicals. The 2510
AIO valve is specially designed to capture a volume of air inside the
system’s mineral tank. Water passes through the AIO valve then
passes through the air head in the top of the mineral tank. Oxygen
from the captured air transfers into the water. The oxygen oxidizes
these contaminates in the water to oxides or solid precipitants. Then
they are mechanically filtered out of the water by the Filox ® media
filter bed. The Filox ® media removes any residual iron, manganese,
and hydrogen sulfide that has not formed into a solid by catalyzing it
quickly into an oxide. After a preprogrammed number of days have
passed, the system will perform a regeneration cycle to clean the
Filox ® media of the solids it has accumulated, draw in more air, rinse,
then return to service. Watts recommends a daily regeneration of the
system. A regeneration every other day may be possible if system
inlet water quality permits (please contact your Watts representative).
Regeneration is as follows:
Backwash (BW): The Backwash cycle washes oxidized contamin-
Cycle Step #1 ates to drain and reclassifies the media bed.
Air Draw (BD): Air Draw empties water from the tank and replen-
Cycle Step #2 ishes the oxygen within the mineral tank.
Rapid Rinse (RR): Rapid Rinse purges excess atmosphere from the
Cycle Step #3 mineral tank and distributor.
Upon completion of Rapid Rinse the system returns to the service
position.
NOTE: Due to the presence of air in the media tank the maxi-
mum operating pressure of the system is 80 psi.
