During the winter months, the population of Marco Island, Florida can double due to tourism, which places an increased
demand on the wastewater treatment facility. In 2007, the existing conventional treatment facility was expanded to a
membrane bioreactor (MBR) since it required an increased treatment capacity but lacked space to expand plant footprint.
The effluent produced at Marco Island exceeds the discharge requirement and provides high-
quality reuse water which is a continuous and reliable supply of irrigation water for golf courses
and residential properties.
Marco Island was selected for testing of the LEAPmbr technology beginning in May 2010.
Process testing was done compared to previous aeration and performance standards. The
results of over a year of testing have demonstrated significant energy savings and productivity
improvements.

The population of Southern Ontario continues to steadily grow, and several membrane bioreactors facilities with GE
ZeeWeed membranes have been installed to treat the increased capacity demand and address tighter regulatory
requirements. An existing MBR facility in Southern Ontario utilizing ZW500d membrane modules was retrofitted with
LEAPmbr technology in early 2011.
Process testing was done to verify product performance at various operating conditions.
Test results showed considerable increased system performance at reduced aeration flow
rates compared to previous aeration methods. Not only that, but LEAPmbr also eliminated
foaming issues that had previously existed at the wastewater facility.
Increased performance, lower energy levels and simplified operation were successfully
demonstrated for LEAPmbr in this full scale application.
