Functions of the parts
Low Pressure Switch**, if the water is cut or if
the pressure is lower than 0.2 bar (3 psi), it
prevents unnecessary operation of the pump.
5M Sediment Filter (350003Z), it retains the
substances and particles floating in water to
make the water clear.
Carbon Filter (350002Z), retains free chlorine,
organic substances and unpleasant odors.
1M Sediment Filter / Carbon Filter (350004Z),
it retains the substances and particles floating in
water to make the water clear.
Automatic Shut-off Valve*** controls the flow of
water. If the system continues to run after the tank
is full, the water is wasted as a waste. This is an
undesirable condition. Water should be cut when
tank capacity is reached. Automatic shut-off valve
cuts the water when the tank pressure reaches a
certain level of the membrane inlet pressure.
Membrane Filter (349004Z) is the place where the reverse osmosis occurs. A long film
made of a semi-permeable material is wrapped onto a reel in two layers. These two layers are
merged together with a separator between the edges of this film with two layers and it is
closed to water passage. It is like a closed long narrow bag except its end wrapped on the reel
with rowed holes that is on the end which allows clean water output only. This double layer
film is wrapped onto a reel. Through the separator film placed between the windings, dirty
water reaches all surfaces of this bag, clean water enters the bag under pressure and taken
from the outlet holes. While dirty water passes by the film surfaces with a flow called
cross-flow, a part of water passes through the internal part of the film as clean water (Figure 3).
