What Factors Affect the Performance of an Ultrapure Water System?

When using an ultrapure water system, a suitable water treatment plan needs to be developed to meet the influent requirements of the ultrapure water equipment and ensure its working performance. Below, we will introduce the factors affecting the performance of ultrapure water equipment and the key indicators to control in the influent.

1. Bacteria: Bacteria feed on cellulose acetate, which can damage the membrane.

2. Iron Content: Higher pH values accelerate oxidation, while lower pH values effectively inhibit oxidation.

3. Particulate Matter: Particles larger than 5µm cannot enter the reverse osmosis unit, otherwise they will damage the membrane.

4. SDI and Turbidity: The lower the SDI, the better; turbidity should be less than 0.2 NTU.

5. Oil and Fat: The raw water must not contain oil or fat.

6. Organic Matter: Activated carbon can be used to remove organic matter from the water. This article discusses the factors that affect the performance of ultrapure water systems. When developing the process for an ultrapure water system, the pretreatment process should be determined according to the quality of the incoming water to ensure the safety of the incoming water.
