Reverse Osmosis Systems


Reverse osmosis systems are the most exquisitefiltration technology among treatment processes. It provides water filtration up to 0.005 micron.


Osmosis is a natural process which is known for thousands years and basis of reverse osmosis. Living cell walls are natural semi-permeable membranes. High content of outer water filters from cell membrane and runs to equalize the water rate and density of both sides. Through membrane’s natural semi-permeable structure, waters transfer is easier than dissolved minerals. Less dense solution desire to delute the more dense solution. Concentration difference occures between both solutions and determines osmotic pressure difference. Due to this pressure difference (2.31 ft water equals to 1psi)0.454 kg pressure units replaces  at per 1”2. It means; 1000 mg/L total dissolved difference equals to 1psi osmotic pressure difference. When pressure applied to more pressured concentrated solution, water pass way reverses and thus,  RO is became applied.


Dissolved salt and little particle content waters pressed tor everse osmosis membranes via high pressure and membranes.While water molecules pass through of membrane pores, dissolved salts, organic matters, heavy metals and bacterias can’t. Substances which can not penetrate the membrane, should be discharged as concentrated wastes. The most important parameter is TDS(Total dissolved solids) at waters which about to treat by Reverse osmosis system. TDS gives us accurate informations about the raw water’s characteristics.All Reverse Osmosis works with same principles. Filtration actualizes while feed flow passesfrom membrane.


Application Fields:

-Obtaining drinking water from sea water

-Obtaining demineralized water

-Preparation industrial process water

-At drinking water production plants

- At fruite juice production plants

- Obtaining low conductivity water at cogeneration systems

-Obtaining pure water forHemodialysis

-Reverse osmosis systems are widely used to recover wastewaters.
