1、反渗透 Reverse Osmosis渗透及反渗透，渗透是一种物理现象，当把含盐水（原水）与纯水用微孔直径为万分之一微米的半透膜隔开时，纯水由于渗透压的作用将透过半透膜而进入原水侧。相反，要是在原水侧施加一种高于其本身渗透压的压力，则原水中的水分子将透过半透膜而进入纯水侧，但原水中的盐水分份、细微杂质、有机物等成分却不能进入纯水侧，这就是反渗透。基于此种原理，人们发明了反渗透膜和反渗透技术，并将其应用于水处理。Permeability and reverse osmosis, infiltration is a physical phenomenon, when the brine (wate
2、r ) and water pore diameter of 1/10000 microns of the semipermeable membrane separated due to osmotic pressure, water will flow through the membrane and into the role of raw water side. Conversely, if the water side exert a higher than its osmotic pressure, then the raw water of water molecules thro
3、ugh the semipermeable membrane and into the pure water side, but in the raw water of saline portion, fine impurities, such as organic matter composition cannot enter the water side, this is reverse osmosis. Based on this principle, a reverse osmosis membrane and a reverse osmosis technology, and its
4、 application in water treatment.Penetration and reverse osmosis, penetration is a physical phenomenon, when the brackish water (raw water) and pure water, pore diameter for the ten thousandth micron semi-permeable membrane separates due to the role of osmotic pressure, pure water through the semiper
5、meablemembrane and into the raw water side. On the contrary, if the raw water side to impose a higher than the osmotic pressure itself, the raw water to the water molecules through a semipermeable membrane into the pure water side, but the raw water to salt water points, minor impurities, organic compounds and other ingredients, but not into the pure water side, which is reverse osmosis. Based on this principle, the invention of reverse osmosis membranes and reverse osmosis technology, and used in water treatment.
