1. APPLICATION

Reverse osmosis process is one of the most advanced technologies of water

purification. Reverse osmosis filter uses a special semipermeable membrane similar in

its structure and properties to the membrane of living cell. It can be conceived of as

having tiny pores that are 200 times finer than virus particle and 4000 times finer than

most bacteria. The principle of reverse osmotic water purification is modelled after

living cell's natural water cycle. It allows to purify drinking water from all harmful

impurities, including nitrates and viruses (see Figure 1 below). Only molecules of

certain size can penetrate cellular membrane.

Ecosoft Robust is a high recovery direct flow operation capable multistage reverse

osmosis system. The system can be equipped with a pressure tank for increasing

purified water flow rate, and multistage design allows to obtain a high recovery of up

to 50%.

The system is tapped in water mains using feed adapter 2 and feed valve 3. Red

tube is run from feed valve to the inlet port in system's port rack (labeled). The port

rack also includes connection ports for the drain, pressure tank 6 (if used), and purified

water faucet 1 or purified water pipe.

Feed water first undergoes prefiltration in sediment prefilter where it is stripped of

suspended particles (rust, sand, hemp strands etc), and carbon prefilter where it is

purified from organic color and chlorine compounds. Pressure gauge no. 1 on front

panel displays water pressure after the two prefilters.

After the prefilters, water goes in pressure booster pump, which sends it in the

membrane array, consisting of three membrane housings arranged in two stages.
