Why is anti pollution roll type reverse osmosis membrane used in the treatment of printing and dyeing wastewater?

The pore size of reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. from water. The cleaning treatment of reverse osmosis membranes is a meticulous and tedious task. Currently, the quality of domestically produced membranes is not high enough, and multiple cleaning of membranes can easily damage them. In order to reduce cleaning work, it is necessary to do a good job in pre-treatment and ensure the quality of water.
