We call this phenomenon as penetration. If the salt water side of the membrane to exert pressure, then the spontaneous flow of water will be inhibited and slowed down, when the pressure reaches a certain value, the net flow of water through the membrane is equal to zero, the pressure is called osmotic pressure. When the exert pressure of saline side is greater than osmotic pressure, then the water flow will be reversed, thus saline water will flow to the water side. The above-mentioned phenomenon is the reverse osmosis basic principles Single-pass Ro system desalination rale≥98%System components Typically the whole system contains pretreatment systems, reverse osmosis devices, post-treatment systems, cleaning systems, and electrical control systems. Pretreatment system generally contains pumps, chemical dosing devices, quartz sand filter, activated carbon filter, and precision filter and so on. Its main role is to reduce the raw water pollution index and residual chlorine in order to achieve the reverse osmosis input water requirements. Device configuration of the pretreatment system should be based on the specific circumstances of raw water. Reverse osmosis unit includes multi-stage high-pressure pump, reverse osmosis membrane element, membrane shell (pressure vessel), frame etc. Its main role is to remove impurities in the water.
