What are the requirements for pre-treatment of reverse osmosis?

Due to the influence of geographical conditions and seasonal climate, the quality of raw water is different, and the characteristics and impurities of raw water are also different. Therefore, the pre-treatment process of reverse osmosis will vary. However, the pre-treatment of reverse osmosis should meet the following requirements:

1. Reverse osmosis pretreatment should be able to remove most of the impurities in the raw water to meet the needs of incoming water;

2. In reverse osmosis pretreatment, changes in water quality should be fully considered to avoid affecting the normal operation of the entire system due to fluctuations in raw water quality;

3. In the process of implementing RO pretreatment, the process should be simplified as much as possible to reduce investment and operating costs;
