Equipment.And water purification is widely used in by us：Life is drunk, chemical industry, medical treatment, cultivation, plantation, food, beverage etc..
Its feature is：
1. reverse osmosiss are at ambient temperature, using the physical method of no phase transformation, brackish water are carried out desalination, desalination.Ultra-thin
The salt rejection rate of compound membrane component can reach more than 99.5%, and can go simultaneously in eliminating water colloid, Organic substance, antibacterial, virus etc.；
2nd, import reverse osmosis membrane is adopted, and salt rejection rate is high, long service life, and operating cost is cheap；
3rd, full-automatic pretreatment system is adopted, realizes Unmanned operation；
4th, high efficiency low noise, reliable and stable；
5th, online water quality monitoring control, real-time monitoring change of water quality, ensure water quality safety；
6th, Full-automatic electric-controlled program, can also match touch screen operation, easy to use；
7th, suit the personalized designs of local water quality, comprehensive meet demand；
8th, occupation area of equipment is little, and the space of needs is also little；
9th, reverse osmosis unit high degree of automation, operation maintenance and plant maintenance workload are little；
10th, the process of water only relies on the pressure of water as motive force, and its energy consumption is minimum in many handling process；

12nd, reverse osmosiss can continuously run controlling the water circulation, simple system, easy to operate, product water stabilization.
Its operation principle is：
Reverse osmosiss are the new membrane separation techniques for growing up the sixties, be rely on reverse osmosis membrane make under stress molten
Solvent and solute in liquid carries out detached process.
It is to be understood that hyperfiltration desalination principle, first it is to be understood that " infiltration " and concept.Infiltration is a kind of physical phenomenon, when two kinds
Water containing variable concentrations salt, such as with a semi-permeable thin film separate it finds that, low salinity one moisture
Can be seeped in the high water of salinity through film, and contained salinity impermeable, so, the salt concentration gradually two is warm
To equalization.However, will complete this process needing very long, this process is also referred to as naturally osmotic.But if in salinity
High water side, examination plus a pressure, its result stops can also above-mentioned infiltration, and pressure at this moment is referred to as osmotic pressure.If
Pressure is increased again, and water can be made to permeate round about, and salinity is remaining.Therefore, reverse osmosis desalination principle, is exactly having salinity
Water in (as raw water), impose the pressure bigger than naturally osmotic pressure, so that infiltration is carried out round about, the water in raw water
Molecule is pressed onto the another side of film, becomes clean water, so as to reach the purpose for removing salinity in water, here it is reverse osmosis desalination is former
Reason.
