Reverse osmosis water treatment is a kind of with the aid of choice through (through) the skill of membrane will return to pressure as the driving
force for a membrane separation technology, when system and the pressure is greater than in the aqueous solution of osmotic pressure, the
water molecules through the membrane unceasingly, after producing water flows into the central tube, and then out in the end the impurities in the
water, such as ion, organic matters, such as bacteria, viruses, interception on the inlet side of the membrane, and then in the thick water outflow
water end, so as to achieve separation and purification.
The operating pressure is applied on the inlet (concentrated solution) side to overcome the natural osmotic pressure. When the operating
pressure higher than the natural osmotic pressure is removed from the concentrated solution side, the flow direction of the natural osmotic water
molecules will be reversed. The water in the inlet (concentrated solution) will pass through the reverse osmosis membrane to become the
purification water produced on the dilute solution side.Reverse osmosis equipment can stop all the soluble salt and organic molecular weight
greater than 100, but allowing water molecules through the reverse osmosis composite membrane desalting rate is generally greater than 98%,
they are widely used in industrial pure water preparation and electronic ultrapure water, drinking pure water production, such as boiler feed water
process, using reverse osmosis equipment before ion exchange can sharply decreasing operation of water and wastewater emissions.
