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
in clear 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.
