The Reverse Osmosis Process is the removal of up to 99.9% of
undesirable water contaminants by forcing untreated water through a
semi-permeable membrane. Pressure forces the water to flow in the reverse
direction to the direction of flow in natural osmosis.
Manufacturers offer cellulose tri-acetate (CTA) systems in
capacities varying from 6 to 20 gallons per day (GPD) which is a perfect
solution when the temperature and the pressure are sufficient to keep the tank
full. The CTA Reverse Osmosis System is the typical solution for city water problems.
The High capacity Reverse Osmosis Systems offer by the manufactures is the
Thin-Film composite (TFC) systems. This is the perfect solution when the water
is very cold, has a high total dissolved solids (TDS) reading or if the water
pressure is low. The TFC Reverse Osmosis System is the typical solution for well water
The Reverse Osmosis system comes in either stages 3, 4, or 5 -
the number varying with the type of Reverse Osmosis unit.
Reverse Osmosis Stage 1
- untreated water passes through a micro pre-filter which removes dirt, dust and
sediment. This stage starts the water cleaning process and also protects the
Reverse Osmosis Stage 2& 3 -
the water passes through a thin film reverse osmosis membrane. This stage
reduces harmful metals and salts including sodium, hard water minerals (calcium
and magnesium) and lead.
Reverse Osmosis Stage 4 - the
water comes off the Reverse Osmosis membrane, passes through an extended contact carbon
filter and then into an under-the-counter pressurized storage tank.
Stage 5 - when
your water faucet is turned on the water in the storage tank is drawn through a
granular activated carbon post-filter to polish the water and improve taste.
