Mitsubishi Chem to supply water-cleaning membrane for SK Hynix

Chipmaker to set up massive industrial water treatment facility

TOKYO -- Mitsubishi Chemical will provide SK Hynix with a water treatment membrane to clean wastewater from a semiconductor plant near Seoul.

The South Korean chipmaker will build one of the world's largest industrial wastewater treatment facilities as it expands capacity at the factory in Icheon, Gyeonggi Province. Related orders to the Mitsubishi Chemical Holdings unit are seen at well over 1 billion yen ($9.17 million).

Mitsubishi Chemical Aqua Solutions, a unit of the Japanese chemical company, will supply hollow-fiber membrane for a so-called membrane bioreactor water treatment facility. This type of facility saves space compared with conventional activated-sludge-process systems, among other advantages. Semiconductor manufacturing requires large amounts of water, and the plant produces 123,000 tons of wastewater per day -- the equivalent of residential wastewater from a city of 600,000.

With the rise of artificial intelligence and robotics, chip production has scaled new heights. Demand for high-efficiency water treatment membrane is only expected to grow as environmental regulations tighten in China and elsewhere.
