• New Facility Will Have Reduced Energy and Maintenance Costs
• LEAPmbr Technology Enables the City of North Las Vegas to Operate the Plant More Efficiently, While Increasing Productivity

TREVOSE, PA.—July 29, 2015—GE (NYSE: GE) today announced it provided the city of North Las Vegas, Nevada, with its high-performance LEAPmbr* membrane bioreactor (MBR) technology for an upgrade to the city’s wastewater treatment plant. By using GE’s LEAPmbr system, the city will reduce its energy and maintenance costs including an estimated 29 percent reduction in membrane scour energy costs. The upgraded water reclamation MBR facility, one of the largest in the United States, treats the municipal wastewater for more than 300,000 of North Las Vegas’ residents and processes up to 25 million gallons of wastewater per day.

With GE’s LEAPmbr and ZeeWeed* 500 membranes, the newly upgraded facility can more efficiently treat the city’s wastewater. Historically, the city of North Las Vegas relied on the city of Las Vegas to treat its wastewater, but in 2012, North Las Vegas built its own plant using GE ZeeWeed membranes and MBR technology. The city then upgraded the facility with LEAPmbr technology three years later to provide the same treatment capacity and high-treated water quality while reducing energy and maintenance costs and increasing productivity.

“Environmental and economic concerns led us to upgrade our wastewater treatment plant with GE’s LEAPmbr technology, which provided us with a more energy-efficient and cost-effective way to operate our facility,” said Dave Commons, water reclamation facility administrator for North Las Vegas. “The retrofit will give us a 29 percent energy reduction on membrane aeration and will save more than $100,000 per year in energy and maintenance costs.”

GE’s LEAPmbr aeration technology provides optimal energy usage by reducing membrane air scour costs along with essentially eliminating cyclic valve maintenance. In addition, the plant’s advanced SCADA system allows the city of North Las Vegas to have minimal staffing at the plant and the wastewater treatment facility can be controlled remotely.

“LEAPmbr is our latest innovation in membrane technology and upgrading to it gives the city of North Las Vegas a more cost-effective and energy-efficient method of aeration. Additionally, LEAPmbr improves water quality, increases water treatment capacity and offers the lowest life cycle costs available from any MBR technology,” said Yuvbir Singh, general manager, engineered systems—water and process technologies for GE Power & Water.

Specifically for the project, GE retrofitted the existing membrane cassettes by supplying LEAPmbr retrofit kits. This allowed the plant to take advantage of the lower air and energy requirements while continuing to get the full life cycle operation out of the originally installed membranes.

LEAPmbr builds on 25 years of experience to deliver the most advanced MBR solution to date. At the core of LEAPmbr is GE’s ZeeWeed 500 membrane, an advanced ultrafiltration technology that separates solids, bacteria and viruses from water or wastewater. GE’s ZeeWeed ultrafiltration membranes offer an unmatched combination of performance, energy efficiency, durability, ease of operation and reliability. More than 1,000 plants worldwide use this technology to produce superior quality water.
