PWBWIRONZ System Overview
PWBWIRONZ systems are selected for use when the concentration
of iron 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 Micro Z ® media
filter bed. After a preprogrammed number of days have passed, the
system will perform a regeneration cycle to clean the Micro Z ® 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.
