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. Activated
carbon particles contain 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 chlorine as
well as other substances that contribute to taste and
odors.
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 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 POST FILTER
–
The
product water from the Holding Tank passes through
the Activated Carbon Post Filter on the way to the
Dispensing Faucet. The Activated Carbon Post Filter
reduces tastes and odors that may pass through the
system. It adds a final “polish” to the water.
AUTOMATIC SHUT–OFF 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.
