NEW ORLEANS, LA - The Yorkville-Bristol Sanitary District (YBSD) in the Fox River watershed in Illinois will be the first customer to use GE’s new ZeeLung membrane aerated biofilm reactor (MABR) technology.

YBSD will use ZeeLung MABR to upgrade the existing activated sludge plant, which has an average flow of 3.62 million gallons per day, to increase its treatment capacity within the existing biological reactors.

The plant is operating near its design load and to accommodate new industries within the city, YBSD sought a cost-effective solution to increase the treatment capacity.

The upgrade, due to be commission in 2017, also involves modifications to enable biological phosphorous removal.

ZeeLung MABR technology employs a gas transfer membrane to deliver oxygen to a biofilm that is attached to the membrane surface. Immersing ZeeLung cassettes into mixed liquor increases the inventory of biomass in a treatment system thereby intensifying the biological treatment process.

Oxygen is delivered to the biofilm by diffusion through the membrane, which reduces the energy required for oxygen delivery by up to four times compared to conventional aeration, GE said.

Kevin Collman, executive director, Yorkville-Bristol Sanitary District, said: "GE’s ZeeLung MABR technology will enable us to increase the treatment capacity within our existing footprint while also reducing the energy consumption of the plant. The Fox River provides our community with recreation and a home for wildlife, and our expansion with ZeeLung also will increase phosphorous removal and help protect the watershed.”

Kevin Cassidy, global leader, engineered systems—water and process technologies for GE Power, said: “When we introduced ZeeLung MABR last year, we knew it was going to be a transformative new technology for municipalities to upgrade wastewater treatment plants for nutrient removal and capacity expansion within existing plant footprints. As our first ZeeLung customer, the Yorkville-Bristol Sanitary District can increase treatment capacity to meet Yorkville’s growing industrial and residential population while also enabling phosphorous removal and reducing energy consumption.”
