The membrane treatment process in sewage treatment is an efficient and advanced treatment technology, whose basic principle is to filter and separate sewage through special membrane materials, thereby removing pollutants from water. The membrane treatment process mainly includes several forms such as microfiltration, ultrafiltration, nanofiltration, and reverse osmosis, and the specific choice of form depends on the water quality characteristics and treatment objectives.

The membrane treatment process has the following advantages:

1. Efficient removal of pollutants: Membrane treatment process can effectively remove suspended solids, dissolved organic matter, microorganisms and other pollutants in water, especially suitable for the treatment of high turbidity water and high concentration organic matter water.

2. Removing heavy metal ions and special pollutants: The membrane treatment process can effectively remove special pollutants such as heavy metal ions, nitrates, and ammonia nitrogen, ensuring stable effluent quality.

3. No secondary pollution: The water quality treated by the membrane treatment process is stable and there is no problem of secondary pollution, which can meet the requirements of different water use fields
