INTRODUCTION
Your new Reverse Osmosis (RO) 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–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 RO Membrane and carbon filter.
REVERSE OSMOSIS MEMBRANE–The RO
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 chlorine tolerant, high flux,
cellulose triacetate (C.T.A.) Membrane. The
spiral wound construction of the RO Membrane
provides maximum surface area for water
production and is less susceptible to fouling by
particulate matter, turbity and colloidal materials.
ACTIVATED CARBON POST FILTER–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 chlorine
as well as other substances that contribute to
tastes and odors. 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.
