Commercial Micro Z™ Filter
Systems
Connection Sizes: 1" to 3" (25 - 80 mm)
Flow Rates: Up to 106 gpm (401 lpm)
Watts Pure Water Series PWM Micro Z™ filters are highly
effective backwashing media filtration systems for the removal
of sediment and suspended solids from water.
They are suitable for commercial applications with flow rates up
to 106 gpm (401 lpm) with media bed sizes ranging from 1 to
20 cubic feet in size. If higher flow rates are required, multiple
units can be installed in parallel. The media bed is cleaned of
captured sediment by periodic backwashing and flushing. This
cleaning cycle is time clock demand initiated and can be pro-
grammed to occur at any time that is convenient for the user.
All steps of the cleaning cycle as well as returning to service
are fully automatic and do not require manual actuation.
Watts Pure Water Series PWM sediment filters are designed for
point of use or point of entry applications where filtered water
is required. Micro Z™ is a naturally occurring form of zeolite
that offers superior filtration characteristics over and above
sand, anthracite and garnet products currently in use today.
The key to Micro Z™’s performance is its hydrophilic proper-
ties combined with a jagged external surface texture. This
gives Micro Z™ a sediment holding capacity of 2.8 times that
of sand, which reduces backwash waste water volumes and
provides higher service flow rates which reduces over all system
size and cost. Micro Z™ has a 3-5 micron nominal particle size
removal rating versus 15-30 micron with other conventional
back-washable medias.
Reverse osmosis pretreatment, micro and ultra filtration system
pretreatment, cartridge filtration pretreatment, sediment reduc-
tion in city and rural water, municipal water filtration, as well as
general turbidity reduction are all common applications for the
Watts Pure Water Series PWM Micro Z™ filter systems.
Filtered water is a cleaner supply water for boilers, solenoid
valves, pumps, faucets, aerator screens, reverse osmosis
systems, micro and ultra filtration systems, pools, aquariums,
washing, and rinsing processes that reduces down time and
costly repairs.
