Reverse Osmosis Desalination Systems

Description:

The reverse osmosis process is based on the fundamental physical principle of equilibrium. Two liquids, of different concentration levels in dissolved salts, come into contact and are mixed to create a homogeneous concentration. When separating the two liquids through a semi permeable membrane, the low concentration liquid will start to move through the membrane towards the high concentration liquid. After a while, the level of the second liquid will be higher  than that of the first liquid. This difference in level is called osmotic pressure.

By submitting the  first column of liquid to a higher pressure than the osmotic pressure, we obtain the opposite  effect: and the liquid is again pressed through the semipermeablemembrane. Applied to the water  that needs treatment, this action will eliminate from the water its dissolved salts.

All our reverse osmosis (RO) membrane filtration systems are skid-mounted and pre-engineered using top quality components producing efficiently treated water with low TDS.
Systems range in output capacities from 10,000 GPD to 1,000,000 GPD (1.6 m³/hr to 160 m³/hr) covering all water purification needs whether domestic, commercial, industrial or municipal.
