Filmtec RO Membrane Filter

Effective in removing ions and organics, reverse osmosis membranes have a higher removal rate than nanofiltration membranes, with reverse osmosis typically removing 99% of the salt from feed water.

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.
