Siemens to Provide Membrane Filtration Systems for Wastewater Reuse for the City of Scottsdale, Arizona, Water Campus

Archer Western Contractors has awarded Siemens Water Technologies with a 7 million US dollar contract to supply 11 Memcor CP membrane filtration systems for the City of Scottsdale, Arizona, Water Campus Advanced Water Treatment (AWT) Facility expansion. The membrane systems will provide Scottsdale with additional capacity within the existing Water Campus building footprint. Siemens will also provide unit control panels and membrane system programming. System installation is scheduled to be completed by August 2011.

The AWT Facility expansion will help meet the increased water reuse supply demands in Scottsdale for the foreseeable future. The new system will be utilized as pretreatment to reverse osmosis for treating wastewater that will be used for both aquifer recharge and irrigation of local golf courses. Each membrane system skid will consist of 222 membrane modules, and will produce a combined total flow rate of 23.5 MGD (88.9 MLD). The 1.8-meter tall PVDF (polyvinylidene fluoride) membrane modules increase the filtrate capacity by over 50 percent, compared to the earlier generation of Memcor pressurized membrane modules. Its compact, modular design allows the system to be easily modified and expanded, and takes up roughly 70 percent less space than conventional water treatment systems.

With this project, the City of Scottsdale and Siemens continue a long-standing partnership that also included the supply of five Memcor CP systems in 2009 for drinking water treatment.
