BRINGING SOLUTIONS TO GLOBAL WATER ISSUES.
Water is an indispensable resource for life. Yet, water pollution caused by domestic and industrial wastewater is a major issue for humans and the environment. Sumitomo Electric develops technologies and products to solve worldwide problems in the aquatic environment and energy industry.
A set of guiding principles were developed and handed down from the Sumitomo Family Enterprise as established in 1882. These principles are still relevant in today’s business environment.
#1 Sumitomo shall achieve prosperity based on solid foundation by placing prime importance on integrity and sound management in the conduct of its business.
#2 Sumitomo’s business interest must always be in harmony with public interest; Sumitomo shall adapt to good times and bad times, but will not pursue immoral business.
Further, the company instills a culture of service and ethical behavior to each member of the Sumitomo Electric Group with the following principles:
- Offer the very best goods and services to satisfy customer needs.
- Build technical expertise, affect positive change, and strive for consistent growth.
- Contribute to creating a better society and environment with a firm awareness of our social responsibility.
- Maintain high corporate ethics and strive to become a company worthy of society’s trust.
- Nurture a lively corporate culture that enables employee self-improvement.

The Story of POREFLON
In 1999, when Sumitomo Electric began working on the development of the POREFLON membrane module, the leading material used in water treatment membranes at the time was polyethylene, known for poor durability and low chemical resistance. PolyTetraFluoroEthylene (PTFE), a product developed by Dupont in the 1960s, was known to excel in those same properties — and others too.
More than 10 years of research led to the development of the POREFLON PTFE MF/UF Membrane made with 100% PTFE, a type of plastic fluororesin that is patented and manufactured exclusively by Sumitomo Electric.
Operating with the distinct advantages of PTFE, the POREFLON module is now commonly used in the most demanding water treatment situations in the world, including urban sewage, industrial organic wastewater, high-concentration of water-insoluble, oil-contaminated wastewater, high TSS and BOD, and highly turbid wastewater.
