Semi-Conductor Industry

In the field of electronic, the production, processing and cleaning of electronic products cannot be achieved without the use of ultra-pure water. With the feature of insulation, the use of ultra-pure water can avoid the short circuit of electronic products, ensure its qualification rate.


In the microelectronics industry, large-scale and ultra-large scale integrated circuits need plenty high-pure water and ultra-pure water to clean semi-finished products or finished products. Higher the integration degree of integrated circuit, higher the requirements of water quality. It makes the requirements stricter on ultra-pure water treatment process, as well as the simplicity, automation degree, continuous production and sustainability of products.


SCHW regards “being a water treatment engineering company with customer satisfaction as primary goal” as the company vision. We provide fast, accurate and perfect services from design, sales, manufacture, engineer installation and after-sale services. Customers can get effective result at ecological and reasonable cost. SCHW can help clients to solve the concerned indicators in ultra-pure water treatment: conductivity, particulate matter, TOC, boron, DO, silicon, bacterial and so on.
