Reverse osmosis water treatment system

Reverse osmosis water treatment system is usually composed of raw water pretreatment system, reverse osmosis purification system and ultra purification post-treatment system. The purpose of pretreatment is to make the raw water meet the water inlet requirements of reverse osmosis membrane separation module and ensure the stable operation of reverse osmosis purification system.

Reverse osmosis membrane system is the most economical and efficient purification method to remove more than 98% ions, organics and 100% microorganisms in raw water at one time. The ultra purification post-treatment system further removes the remaining trace ions, organics and other impurities in the reverse osmosis pure water through a variety of integrated technologies, so as to meet the final water quality index requirements for different purposes.
