MBR technology to reduce energy costs for Nevada treatment plant
GE has supplied its high-performance LEAPmbr membrane bioreactor (MBR) technology for an upgrade to the North Las Vegas wastewater treatment plant in Nevada in the US. Installation of the technology will help reduce the North Las Vegas' energy and maintenance costs, including an estimated 29% reduction in membrane scour energy costs.
The upgraded water reclamation MBR facility is one of the largest in the US, treating municipal wastewater for more than 300,000 of North Las Vegas’ residents and processing up to 25 million gallons daily.
The LEAPmbr aeration technology provides optimal energy usage by reducing membrane air scour costs along with essentially eliminating cyclic valve maintenance. Also, 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.
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.
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.
“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% energy reduction on membrane aeration and will save more than $100,000 (£64,000) per year in energy and maintenance costs.”
