Product description

The reverse osmosis water treatment equipment usually consists of a raw water pretreatment system, a reverse osmosis purification system, and an ultra-purification post-treatment system. The purpose of pretreatment is to make the raw water reach inflow requirement of the reverse osmosis membrane separation module and ensure the stable operation of the reverse osmosis purification system. The reverse osmosis membrane system is the most economical and efficient purification method, which can remove 98% or more of ions, organic matters and 100% microorganisms in the raw water at one time. The ultra-purification post-treatment system further removes residual ions and organic substances remaining in the reverse osmosis pure water through various integration techniques, so as to meet the final water quality index requirements on different purposes. Reverse osmosis is the most precise membrane-based liquid separation technique. Operating pressure is applied to the influent (concentrated solution) side to balance natural osmotic pressure. When the operating pressure higher than the natural osmotic pressure is applied to the concentrated solution side, the natural infiltration direction of water molecules will be reversed. Water molecules in the influent (concentrated solution) will pass through the reverse osmosis membrane, becoming purified water on the dilute solution side. The equipment can block all dissolved salts and organic matters with molecular weight greater than 100, but allow water molecules pass through, making the desalination rate of reverse osmosis composite membrane generally greater than 98%. They are widely used in industrial pure water and electronic ultra pure water preparation, portable purified water production, boiler feed water and other processes. Adopting reverse osmosis equipment before ion exchange can greatly reduce the discharge volume of operating water and waste water.
