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.
