Get PriceOverall UPW market expected to grow through 2010. By Robert McIlvaine and Alpa Bagga, The McIlvaine Company. In the semiconductor industry, ultrapure water is used for cleaning and etching of wafers. Wafer rinsing, in particular, is responsible for the largest consumption of …
Get Price2019-3-5u2002·u2002In the semiconductor industry, there are many product processes. The wastewater rejected from reverse osmosis/continuous electrodeionization systems (RO/CEDI) is considered to be relatively clean and easy to treat and recycle. An RO/CEDI system is designed for producing ultra-pure water (UPW) from any feed water stream.
