Sumitomo Electric Industries, Ltd. is pleased to announce that we have received orders for delivering our proprietary POREFLON® modules to three major wastewater treatment facilities in China. All of these projects are among the largest in our water treatment business.

Since the establishment of the Water Pollution Prevention Action Plan in 2015, China has been actively promoting water pollution preventive measures such as stringent pollutant emission control. Sumitomo Electric has been actively working to develop this business in China since 2008 and has now won contracts for the following three major projects for wastewater treatment.

A critical issue for membrane bioreactor (MBR),* a widely used wastewater treatment method in large-scale plants, is how to reduce energy costs in cleaning the membrane. To counter this problem, Sumitomo Electric's POREFLON® modules, which increased the size and packing density of high-strength, flexible hollow fiber membranes, reduce the amount of air required for stable membrane treatment and thus save energy. In addition, the compact design reduces the installation footprint and thus construction costs. These excellent features are appreciated by our customers and resulted in our winning these three contracts.

Sumitomo Electric continues to strive to supply high-quality products, solve water treatment problems not only in China but also around the world, and contributes to environmental preservation of Earth, the "Water Planet."

* Membrane bioreactor (MBR):
A wastewater treatment system combining biological treatment with activated sludge and physical treatment by membrane separation, which can provide excellent water quality and operational management and greatly reduce the installation footprint of the wastewater treatment facilities.
