Construction firm GHD is using GE's LEAPmbr membrane bioreactor (MBR) technology to upgrade the Brush Creek sewage plant in Cranberry Township, Pennsylvania, US.
The upgrade to the Brush Creek sewage plant will help in meeting stringent state and federal phosphorous and nitrogen discharge regulations.
Currently, the facility treats about 3.4mllion gallons of wastewater per day. The upgraded plant will have the capacity to treat more than 7 million gallons of wastewater per day.
There are also plans to expand the project in the future to treat about 8.73 gallons of wastewater per day with an organic capacity of 19,200 pounds per day.
Cranberry Township public works director Jason Dailey said: “Cranberry Township's population is steadily growing, and the expansion of the Brush Creek Water Pollution Control Facility will ensure we can treat the wastewater now and in the future as well as meet more stringent phosphorus and nitrogen discharge limitations.
“Working with GHD and installing GE’s LEAPmbr technology will enable our plant to run more effectively and efficiently.”
The facility offers wastewater treatment services to Cranberry Township along with parts of Pine, Marshall and New Sewickley Townships. Wastewater first collected from homes, businesses and industries from these areas is treated and released into Brush Creek.
GE Power engineered systems—water and process technologies global leader Kevin Cassidy said: “LEAPmbr is ideal for municipalities that want to decrease their overall capital and life cycle costs and increase productivity all within a smaller footprint.
“After the upgrade, Cranberry Township will be able to provide its residents and industrial businesses with improved effluent water quality, increased treatment capacity and a lower cost of ownership.”
In an other development, GE announced that the Yorkville-Bristol Sanitary District (YBSD) in the Fox River watershed in Illinois is the first customer for its new ZeeLung membrane aerated biofilm reactor (MABR) technology.
YBSD offers wastewater collection and treatment services for the city of Yorkville, Illinois. Its treatment facility is an activated sludge plant with a design average flow of 3.62 million gallons per day.
The district will use ZeeLung MABR to upgrade the existing facility for increasing its treatment capacity within the existing biological reactors.
The upgrade also includes changes to allow biological phosphorous removal.
