Series PWC

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 dechlorination 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 backwashing 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 membranes 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 activated 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 superior 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 production, soft drink water processing, reverse osmosis pretreatment, ion exchange resin pretreatment, and general dechlorination of municipal water.

Specifications

Watts Pure Water Series PWC activated carbon filter system shall be installed on the building’s main water line just after it enters the building. The installation point shall be after any backflow prevention or pressure regulating valves. Other installation options are to install a system just before the plumbing equipment or processes requiring dechlorinated water. In installations where the dedicated cold water make up to a water heater is the installation point, a backflow preventer and a thermal expansion tank must be installed as well. The system shall be installed with a bypass valve to allow for the shut down and removal of the unit without interrupting the water supply to the building. The filter system shall be a backwashing granular media bed type with digital programmable time clock initiated backwash and high capacity coconut shell carbon filter media. The car-

bon media shall be rated at 1,050 m²/g minimum surface area

and have a minimum iodine number of 1,000. The system shall include all components necessary for proper operation.

Electrical requirements are 120 volt 60 hertz. A local drain is

required to accept drain water from the system. The feed water pressure must not fall below 30psi or exceed 125psi. Water temperature must not fall below 34°F or exceed 110°F (1 - 43°C).

Notes: Flow rates are calculated at a 2 minute empty bed contact time (EBCT) for chlorine reduction. Do not use flow rates stated above for reduction of chloramines or organic compounds. Chloramines reduction requires a 17-22 minute EBCT. EBCT for organic compound reduction varies by organic compound. Pipe size, tank size, and space requirements are in inches.
