In the production of chips, transistors and integrated circuits, water is mainly used for cleaning and washing contaminated impurities on the surface of silicon wafers, and a small amount of water is used for pharmaceutical liquid preparation, stream, cooling, plating solution configuration. The quality of water is closely related to the product quality and yield of integrated circuits, that high purity water is used to clean silicon wafers in 80% of the integrated circuit production process. Especially for chip manufacturing, the requirements for water quality are strict, that the more high-end chips production, the higher requirements for water quality. TOC, DO, boron, silicon and metal ions in industrial water will affect the quality of chip production.

In some new materials based on biological fermentation and polymerization, separation technology is the key development and production process. This kind of green polymer material has broad application field and market prospect because of its special physical properties and degradability. The effect of separation and concentration directly affects the yield and concentration of intermediate, which is related to the quality and cost of the final product.
