Commercial Carbon Filter Systems
Connection Sizes: 1" to 3" (25 - 80mm)
Flow Rates: Up to 129 gpm (488 lpm)
Watts Pure Water Series PWC activated carbon filters are
highly effective backwashing media filtration systems for the
removal of chlorine as well as taste, odor, and color caused by
organics, from water.
They are suitable for commercial applications with dechlorina-
tion flow rates up to 129 gpm (488 lpm) with media bed sizes
ranging from 1 to 35 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 backwash-
ing and flushing. This cleaning cycle is time clock demand
initiated and can be programmed 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 PWC activated carbon filters are
designed for point of use or point of entry applications where
dechlorinated water is required. Chlorine, an oxidizing agent,
is added to municipal water to destroy micro-organisms.
Chlorine causes the destruction of reverse osmosis mem-
branes and polymer based ion exchange resins. Chlorine also
causes objectionable tastes and odors in certain applications.
Activated carbon in general is used for dechlorination, removal
of taste, color, and odor caused by organics, as well as trace
hydrocarbon removal from water. For applications involving
trace hydrocarbon removal or taste, color, and odor removal
due to organics, consult your Watts representative for proper
sizing and carbon system selection. Watts Series PWC acti-
vated carbon filters utilize 12x40 mesh coconut shell carbon
granules which are tailored for chlorine removal. Coconut shell
carbon media has a high micro-porosity which makes it ideally
suited for the removal of low molecular weight contaminants
such as chlorine. Another advantage of this carbon is its supe-
rior hardness, which combined with a de-dusting process in
its production, creates an exceptionally clean product with low
fines.
These systems are ideal for food and bottled water processing,
restaurant drink station water treatment, commercial ice pro-
duction, soft drink water processing, reverse osmosis pretreat-
ment, ion exchange resin pretreatment, and general dechlori-
nation of municipal water.
