Brief Introduction
Reverse osmosis membrane separation technology uses the principle of reverse osmosis membranes to separate solutes and water at room temperature without phase change, and is suitable for the separation and concentration of heat sensitive substances, with lower energy consumption compared to separation methods with phase change.
Reverse Osmosis Membrane/8" Water Treatment Membrane, which have a high desalination and water reuse rate, can retain solutes with particle sizes of several nanometres or more.

First of all, you should have a water pressure meter, you test the pressure of the waste water, if the pressure value is above 6KG, it means that the RO membrane may be blocked. Or you have a TDS or conductivity meter, you test the water quality if the TDS value of the water is very high, then the d
