HOW YOUR REVERSE
WORKS
Introduction: Your Reverse Osmosis (RO) Drinking
Water System uses your household water pressure
to force water through three filters. Minerals and
impurities are filtered out. Delicious tasting drinking
water goes to the storage tank-ready for your use.
Minerals and impurities are sent down the drain. The
following paragraphs will explain in detail how your
Reverse Osmosis Drinking Water System works.
Pre-filter (Cartridge 1): Water from the cold supply
pipe enters the pre-filter. See Fig. 23. The pre-filter
has a replaceable sediment cartridge with activated
carbon in its composition. The cartridge reduces
taste, odor, sand, silt, dirt, other sediments, and up
to the amount of chlorine shown in the specifications.
Reverse Osmosis Membrane Cartridge: Filtered
water flows from the pre-filter to the Reverse
Osmosis membrane cartridge. See Fig. 23. The
Reverse Osmosis cartridge is a tightly wound special
membrane. The membrane reduces the dissolved
solids and organic matter. High quality product water
(about 30 ml per minute) exits the Reverse Osmosis
membrane cartridge. The product water flows to the
storage tank, postfilter or Reverse Osmosis faucet.
Drain water, with the dissolved solids and organic
matter, is routed to the drain.
Storage Tank: The storage tank holds product water.
See Fig. 23. A diaphragm inside the tank holds water
pressurized to about half of supply water pressure
when the tank is full. This provides fast flow to the
Reverse Osmosis faucet. When the tank is empty of
water, the pressure at the air valve is 0.35 - 0.48 bar.
Post-filter (Cartridge 2): Water goes through the
postfilter before going to the Reverse Osmosis
faucet. See Fig. 23. The post-filter is an activated
carbon type filter. Any remaining tastes and odors are
reduced from the product water. Clean, high quality
drinking water is available at the faucet.
Reverse Osmosis Faucet: The sink or countertop
faucet has a hand operated knob to dispense drinking
water. See Fig. 23.
How Your RO Water System Works
OSMOSIS SYSTEM Shutoff Assembly: The unit has an automatic shutoff
system to conserve water. When the storage tank
has filled to capacity, and the drinking water faucet
is closed, pressure closes the shutoff to stop flow to
the drain.
After enough drinking water is used, pressure in the
system drops, and the shutoff opens to allow the tank
to be refilled. See Fig. 23.
Check Valve: A check valve is located in the Reverse
Osmosis manifold above the center cartridge. The
check valve prevents a backward flow of product
water from the storage tank to drain. A backward flow
could damage the Reverse Osmosis Membrane. See
Fig. 23.
Flow Control: Water flow to the drain is restricted by
the flow control. It maintains the desired flow rate to
obtain the highest quality drinking water. The flow
control is located inside the elbow fitting on the
Reverse Osmosis manifold drain port. See Fig. 23.
