NSF/ANSI thumbs-up for residential MBR system

Kansas-based Bio-Microbics Inc, which makes decentralized wastewater treatment systems, has achieved NSF®/ANSI® 350 certification for its Bio-Barrier® membrane bioreactor (MBR) designed for residential and small-flow developments.

Scientists from NSF International conducted an evaluation spanning more than six months of continuous operation of the MBR treatment system at one of its approved wastewater-testing facilities.

As one of the first systems to comply with applicable standards, the goal of Bio-Microbics with the BioBarrier system is to use decentralized treatment technology for the benefit of water-reuse projects that reduce fresh water consumption and minimize effluent discharge. Integrated systems with reuse opportunities contribute more to water savings, which are significant over time as water recycles through the system, allowing for less dependence on potable water sources.

Certification to the new NSF/ANSI 350 satisfies requirements for leading US green building programs including USGBC LEED® (Leadership in Energy & Environmental Design) for Homes (2008) Water Efficiency credit for graywater-reuse systems. Products certified to NSF/ANSI 350 could also satisfy graywater-use strategies under the National Association of Home Builders (NAHB) National Green Building Certification program as an innovative practice.

“Bio-Microbics is pleased to receive the NSF-350 mark for Water Reuse,” says Bob Rebori, president of Bio-Microbics. “In relation to the other NSF marks we have acquired through thorough testing of NSF Standards 40 and NSF 245 for nitrogen reduction, the 350 mark offers qualitative advantages for products that bring about positive benefits for water reuse.”

Biobarrier is available in three sizes: 500 GPD (1.89 m³/d), 1,000 GPD (3.78 m³/d) and 1,500 GPD (5.66 m³/d).
