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.
