Dow Ultrafiltration Awarded Water Recycling/Reuse Certification
Ultrafiltration SFP-2880 module certified for water recycling and reuse applications by California Department of Public Health
Dow Water & Process Solutions, a business unit of The Dow Chemical Company, announced the acceptance of the Dow Ultrafiltration SFP-2880 module for water recycling applications. The approval certifies Dow Ultrafiltration as an acceptable filtration technology in compliance with the California Water Recycling Criteria (California Code of Regulations, Title 22).
California Water Recycling Criteria recognizes membrane filtration as an acceptable filtration technology provided prescribed performance requirements are reliably met. Performance criteria through testing must demonstrate the filtered wastewater not exceed 0.2 Nephelometric turbidity units (NTU) more than 5% of the time within a 24-hour period and 0.5 NTU at any time.
"Receiving this certification from the state of California for our highest productivity pressurized ultrafiltration element reaffirms Dow’s commitment to sustainability," said Fabrien Creus, strategic marketing manager for Dow Water & Process Solutions. “Water scarcity and quality are two significant issues facing our world today, and we’re pleased that our high-quality ultrafiltration technology is setting the standard around recycled water.”
The DOW Ultrafiltration SFP-2880 offers 50% more membrane active area while decreasing the required system footprint by 30%, the company said. The SFP-2880 adds 20 in. of length when compared to the Dow Ultrafiltration SFP-2860, but allows flexibility in system design by reducing the number of modules, required piping, skid infrastructure and the size of the compressed air and clean in place systems. In addition, the larger modules produce a smaller waste stream for disposal.
