The role of reverse osmosis technology in industrial wastewater treatment

Dec 09, 2020

Reverse osmosis is also called reverse osmosis. It is a membrane separation operation that uses pressure difference as the driving force to separate solvent from solution. Because it is opposite to the direction of natural penetration, this technique can also be called reverse osmosis. According to the different osmotic pressure of various materials, the reverse osmotic pressure greater than the osmotic pressure can be used to achieve the purpose of separation, extraction, purification and concentration. Reverse osmosis technology is also widely used in chemical wastewater treatment. This technology can not only greatly reduce chemical production costs and protect the environment, but also further realize many meanings such as wastewater recycling. Because reverse osmosis membrane technology has relatively high requirements for influent water, when using reverse osmosis technology for advanced treatment of chemical wastewater, workers also need to combine sedimentation, coagulation, microfiltration, ultrafiltration, activated carbon absorption, and pH adjustment. And other pretreatment processes, so that the wastewater treatment effect is better.
