RO reverse osmosis membrane water purification operation costs and labour costs are low, reducing environmental pollution. The change in water quality due to fluctuations in source water quality is mitigated, thus contributing to the stability of water quality in production, which has a positive effect on the stability of pure water product quality.

Product Advantages
1. High desalination and water reuse rates, and can retain solutes with particle sizes of several nanometres or more.
2. The separation of solutes and water can be carried out at room temperature without phase change, which is suitable for the separation and concentration of heat-sensitive substances and has lower energy consumption compared to separation methods with phase change.
3. The use of low pressure as the membrane separation power, so the separation device is simple, easy to operate, maintain and self-control, site safety and health.
4. Reverse osmosis membrane separation technology has a wide range of impurity removal.

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
