1. PURPOSE OF THE PRODUCT

Reverse osmosis is by far the most advanced technology of water purification in use today. Special
semipermeable membrane structure similar in its properties to the membrane of a living cell
is capable of purifying drinking water from virtually all harmful impurities (see Figure 1). The
membrane can be conceived of as having tiny pores, 200 times smaller than viruses and 4000
times smaller than bacteria. Domestic water filters with reverse osmosis membranes harness the
principle of body's metabolism on a cellular level. Only molecules of certain size can penetrate
cellular membrane.

Direct flow reverse osmosis filter CROSS 90 is a four-stage in three steps filtration unit with
three cartridges functioning as follows (see section (2.3) for reference numbers). Filter rack is
connected to cold water supply with feed water adapter (4). White tube (3/8") carries water from
feed valve through low pressure switch and inlet solenoid valve to the CF filter cartridge. Incoming
water then passes through pre-filter cartridge (7). Pre-filter cartridge is a complex cartridge with
(2) stages inside. It is designed to remove solids (such as rust, sand, silt, etc), residual chlorine,
and organochlorines from water. After undergoing pre-treatment steps in the pre-filter, water
enters into the third (and the most important) stage: reverse osmosis membrane (7) contained in
a cartridge RO. One of the two outlets supplies purified water (permeate), and the other carries
away water with rejected impurities (concentrate). The membrane purifies water at the molecular
level by passing through its pores only the water molecules and the molecules of dissolved oxygen.
