Basic components common to all reverse osmosis
water filters
  • Reverse osmosis water filter comes in all shapes
    and brands but the basic components are more or
    less similar for all the different makes.

3
Common basic components
  • Reverse osmosis water filter water inlet valve
  • Reverse osmosis water filter pre-filters
  • Reverse osmosis water filter membrane
  • Reverse osmosis water filter storage tank
  • Reverse osmosis water filter post filter
  • Reverse osmosis water filter automatic shut off
    valve
  • Reverse osmosis water filter check valve
  • Reverse osmosis water filter flow restrictor
  • Reverse osmosis water filter faucet
  • Reverse osmosis water filter drain line

4
Reverse osmosis water filter water inlet valve
  • This is the valve that connects the reverse
    osmosis water filter to the water supply line
    that supplies water to your home. The valve is
    connected to the water inlet by a tube. This is
    the water source that supplies water to be
    processed by the filter.

5
Reverse osmosis water filter pre-filters
  • These pre-filters are fixed before the water
    filter so that water from the supply line pass
    through the pre-filters to remove all unwanted
    particles.
  • Normally carbon pre-filters are used to remove
    chlorine which may harm the semi-permeable
    membrane.
  • Pre-filters are used to protect the
    semi-permeable membrane beside filtering out
    silk, dirts and other sediment.

6
Reverse osmosis water filter membrane
  • The semi-permeable membrane will remove all
    impurities by applying pressure to the water to
    force it through the tiny pores of the membrane
    which is usually around 0.0001micron.
  • There are two types of membrane which are
    normally used.
  • Cellulose Triacetate (CTA) is tolerant to
    chlorine and Thin Film Composite (TFC) which is
    not tolerant ot chlorine.

7
Reverse osmosis water filter storage tank
  • Processed water are stored in a storage tank
    which can hold up to 2.5 gallons of water.
  • There is a bladder to keep the pressure in the
    water tank when the tank is full.

8
Reverse osmosis water filter post filter
  • Carbon or activated carbon post filter is used as
    to filter the purified water that comes from the
    storage tank.
  • This post filter will remove any odour or taste
    from the water before leaving the water filter to
    the faucet.

9
Reverse osmosis water filter automatic shut off
valve
  • This shut off valve will stop the water from
    entering the membrane when the storage tank is
    full and stops the filtering process.
  • The outflow of waste water also stops.
  • When purified water is drawn from the storage
    tank, the pressure in the tank reduces and the
    valve opens to allow the purifying process to
    begin and waste water being released to the drain.

10
Reverse osmosis water filter check valve
  • This check valve is fixed at the outlet of the
    water filter membrane housing.
  • This valve will prevent any backward flow of
    purified water from the storage tank to the
    membrane.
  • Backward flow would damage the membrane.

11
Reverse osmosis water filter flow restrictor
  • This flow restrictor regulates the flow of water
    through the membrane to produce the highest
    quality of purified water.
  • Without this device located at the drain line
    tube, very little purified water will be produced
    as water from the supply line will simply flow
    down the drain line where there is less
    resistance.

12
Reverse osmosis water filter faucet
  • The water filter has its own faucet installed at
    the kitchen sink where drinking water can be
    drawn.

13
Reverse osmosis water filter drain line
  • This drain line is connected to the outlet of the
    water filter membrane housing.
  • This line allows the waste water which contains
    all impurities and contaminants  which was remove
    from the tap water during the purifying process.
