Sumitomo Electric Wins Three Major Projects for Wastewater
Treatment in China
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 businessin 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 ourwinning 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 toenvironmental preservation of Earth, the “Water Planet.”* Membrane bioreactor (MBR): A wastewater treatment system combining biologicaltreatment with activated sludge and physical treatment by membrane separation, which
can provide excellent water quality and operational management and greatly reduce theinstallation footprint of the wastewater treatment facilities.
