Greensboro, N.C. (Oct. 17, 2011) – Anua, formerly Bord na Mόna Environmental Products U.S., received approval under California Recycling Criteria Title 22 from the State of California Department of Health for its PuraM® membrane bioreactor (MBR) as an alternative filtration technology.
The Title 22 regulation requires technologies meet certain specifications for recycled water filtration applications. North Carolina State University tested the PuraM at the Bord na Móna Innovation Center at the TZ Osborne Water Reclamation Facility in Greensboro, N.C. to confirm compliance under California Title 22. The testing showed that the PuraM MBR system met or surpassed the requirements under Title 22.
The PuraM MBR uses flat plate membranes assembled into 50-plate membrane cassettes submerged vertically in an activated sludge aeration basin. The PuraM uses a polyethersulfone ultrafiltration membrane with a polyethylene/polypropylene backing material. The PuraM nominal pore size is 0.05 microns with an operational flux rate of 11 gpd/ft2. The system, which does not require back-pulse cleaning or routine chemical cleans, achieves reuse quality water with BOD, TSS and total nitrogen levels of less than 5 mg/l.
The PuraM MBR is engineered specifically for the decentralized municipal and commercial water reuse market.
'We’re especially proud of this approval as Title 22 is the highest standard against which reuse technologies are measured,' said Anua President Shane Keaney.
“When we changed our name to Anua earlier this year, we said the move reflected a renewed commitment to provide sustainable products that help communities, municipalities and industries manage their environmental impact more effectively and cost-efficiently,” he continued. “This approval is right in line with that goal as we promote water reuse initiatives throughout the country.”
With headquarters in Greensboro, N.C., Anua develops and markets decentralized wastewater treatment, water reuse and odor control solutions for single-family homes, communities, municipalities and industries throughout North America. Combining recycled or waste materials with innovative technology, the company’s products help customers ensure clean air and clean water while reducing the demand for energy and the use of chemicals. Part of the Ireland-based Bord na Móna Group, Anua began its U.S. operations in 1993.
