What Issues Need to Be Addressed Before Raw Water Enters the Ultrapure Water System?

Before water enters an ultrapure water system, it needs to undergo certain treatments to ensure the safety of the incoming water. So, what issues need to be addressed before the raw water enters the ultrapure water system?

1. Sedimentation: We can use a large-capacity, low-flow-rate natural sedimentation method.

2. Coagulation: We can use high-molecular-weight coagulants such as iron and aluminum to react with impurities in the water through bridging, forming large precipitates that are then removed by other equipment.

3. Filtration: Specialized equipment is used to intercept impurities in the water before further removal.

4. Softening: We use chemical agents and cation exchange resins to soften the water.

The above is an introduction to the issues that need to be addressed before the raw water enters the ultrapure water system. We hope this information is helpful. The reverse osmosis membrane in an ultrapure water system has very high requirements for water quality; direct intake of raw water can damage the system, so proper pretreatment of the raw water is essential.
