SECTION I. 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 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 Holding 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.
WATER QUALITY MONITOR
–The optional
Water Quality Monitor has been integrated into
