INTRODUCTION
Your new Reverse Osmosis (R.O.) Drinking Water
System uses a combination of filtration technologies
to reduce unwanted contaminants in a water supply.
The following steps combine to give you the best
inclear sparkling drinking water:
MECHANICAL FILTRATION/ACTIVATED
CARBON–The sediment prefilter will remove
the larger particles such as silt, rust and scale. Its
5 micron (equal to 0.0002 inch) nominal rating
helps to give maximum life to the R.O.
Membrane. The activated carbon in the Prefilter
will remove any chlorine that may be present in
the feed water. This pretreatment is also necessary
for membrane protection.
REVERSE OSMOSIS MEMBRANE–The R.O.
Membrane is the heart of the filtration system. It
is designed to reduce the dissolved mineral
content of the water. Minerals picked up in the
environment by the water are measured as Total
Dissolved Solids (TDS). In the Reverse Osmosis
process, dissolved minerals are separated from the
incoming water (Feed Water) to produce the
product water (the Permeate). The excess
minerals are rinsed to drain (the Reject Water).
The membrane is a specially constructed, fully
aromatic polyamide film and is classified as a Thin
Film Composite (T.F.C.).
The spiral wound construction of the R.O.
Membrane provides maximum surface area for
water production and is less susceptible to fouling
by particulate matter, turbidity and colloidal
materials.
ACTIVATED CARBON–The Activated
Carbon Post Filter contains carbon particles with
a vast network of pores. The tremendous surface
area of these pores (typically 800–1200 square
meters per gram of carbon) gives the carbon very
good adsorptive sites for substances that
contribute to tastes and odors.
IN–LINE ACTIVATED CARBON POST
FILTER–The In–Line Activated Carbon Post
Filter is located after the Holding Tank and
reduces the tastes and odors that may pass through
the system. It adds a final polish to the water.
AUTOMATIC SHUTOFF VALVE–The
ASO Valve senses when the product water tank is
full and closes the feed water supply to prevent
excess reject water from going to drain when the
unit is not producing water.
