REVERSE OSMOSIS SYSTEM INSTALLER AND USER GUIDE

1. PURPOSE OF THE PRODUCT

Reverse osmosis is by far the most advanced technology of water puricaon in use today.

Special semipermeable membrane structure similar in its properes to the membrane of a living

cell is capable of purifying drinking water from virtually all harmful impuries, including nitrates

and viruses (see Figure 1). The membrane can be conceived of as having ny pores, 200 mes

smaller than viruses and 4000 mes smaller than bacteria. Domesc water lters with reverse os-

mosis membranes harness the principle of body’s metabolism on a cellular level. Only molecules of

certain size can penetrate cellular membrane.

Reverse osmosis system is a ve-stage ltraon unit funconing as follows (see secon 2.4 for

reference numbers). Filter rack is connected to cold water supply with feed water adapter 4 and

feed valve 5. Red tube carries water from feed valve to the (rightmost) bulb lter rack. Incoming

water then passes through pre-lter cartridges 9. Pre-lter cartridges are designed to remove sol-

ids (such as rust, sand, silt, etc), residual chlorine and organochlorines from water. Aer undergo-

ing pre-treatment steps in the pre-lters, water enters into the fourth (and the most important)

stage: reverse osmosis membrane 11 contained in a special housing. Inlet of membrane housing is

connected with the third (lemost) bulb lter rack through the feed side of auto shut-o valve

(four-way valve fastened to the top of lter rack). One of the two outlets supplies puried wa-

ter (permeate), and the other carries away water with rejected impuries (concentrate). The

membrane puries water at the molecular level by passing through its pores only the water

molecules and the molecules of dissolved oxygen.
