2Basic 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.
3Common 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
4Reverse 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.
5Reverse 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.
6Reverse 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.
7Reverse 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.
8Reverse 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.
9Reverse 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.
10Reverse 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.
11Reverse 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.
12Reverse osmosis water filter faucet
- The water filter has its own faucet installed at
the kitchen sink where drinking water can be
drawn.
13Reverse 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.
