systems apart from other reverse osmosis systems. It is not enough to include any commercial grade

resins; the blend of cationic and anionic resins must be nuclear grade and carefully engineered to match

the reverse osmosis membrane.

Stage Five

Following the DI resins are four inches of granular activated carbon to polish the product water for a

clean, fresh taste. The ﬂ ow rate at this stage provides tremendous contact time to assure complete remov-

al of any remaining organic contaminates.

Stages Six and Seven

The ﬁ nal two stages of our proprietary DI module are included to prevent the reverse migration of con-

taminates into the system. The incorporation of these stages further separates the BEV systems from other

manufacturer’s designs. After carefully combining the elements of the previous ﬁ ve stages it is essential to

integrate these stages to assure contaminates cannot enter the system from the product water end.

COMPONENT DESCRIPTION

Following is a brief description of the main components of your PWS™ BEV-300 Series system.

Feed Water Saddle Valve

The feed water saddle valve provides a simple and effective method of connecting your new PWS™ BEV-

300 Series system to most existing home plumbing. Easily attached, the clamp-on valve includes a pierc-

ing mechanism which allows you to tap into the cold water supply line without having to drill holes or

unscrew existing ﬁ ttings.

Drain Saddle Valve

The drain saddle valve included in the installation kit provides a simple and secure method of attach-

ing the brine water discharge from your BEV-300 system to the existing drain line. Like the feed water

saddle valve, this valve is easily attached and does not require disassembly of existing plumbing ﬁ xtures.

Sink Mounted Chrome Faucet

The long reach chrome faucet included in your installation kit is made from the highest quality lead-free

materials and is designed to provide years of trouble free service.

Sediment Pre-ﬁ lter

Our spun-polyester dual gradient (10-20 micron) industrial grade pre-ﬁ lter is designed to remove silt,

sand, rust, scale and other suspended particulates. It has a much higher dirt holding capacity when

compared to sediment pre-ﬁ lters included in most other RO systems. This allows the ﬁ lter to contain

considerably more suspended contaminants before fouling or reducing throughput to the downstream

components.

Granular Activated, Unidirectional, Carbon Pre-ﬁ lters

Only Pure Water Systems offers dual, unidirectional, GAC pre-ﬁ lters where ﬂ ow is engineered to be

lengthwise—not radial like most other designs. Lengthwise ﬂ ow insures maximum contact time pro-

viding for total removal of any dissolved organic compounds present in the feed water. By placing two

pre-ﬁ lters in series, we also insure complete chlorine conversion protecting the reverse osmosis mem-

brane which follows.

RO Pressure Vessel

The pressure vessel houses the polyamide thin-ﬁ lm-composite reverse osmosis membrane. The design

provides a means to collect the puriﬁ ed product water and an exhaust opening to drain off the concen-

trated brine water.
