Siemens' MBR plant to help keep Italian coastline pristine

Siemens Water Technologies will supply Mediterranea delle Acque's new WWTP in Santa Margherita Ligure and Portofino, Italy with pretreatment to a membrane bioreactor (MBR) system. Housed partially underground, the plant will benefit the coastal villages' fishing and tourism industries by producing high-quality effluent that can be used for a variety of reuse purposes. Once it comes online in 2009, the 3 million Euros system will be Siemens' largest MBR installation in Europe...

WARRENDALE, PA, March 4, 2008 -- Siemens Water Technologies will supply Mediterranea delle Acque's new wastewater treatment plant (WWTP) in Santa Margherita Ligure and Portofino, Italy with pretreatment to a membrane bioreactor (MBR) system. Housed partially underground, the plant will benefit the coastal villages' fishing and tourism industries by producing high-quality effluent that can be used for a variety of reuse purposes. Once it comes online in 2009, the 3 million Euros system will be Siemens' largest MBR installation in Europe.

Located off the Ligurian Sea, the MBR plant will be able to easily meet fluctuating water demands from seasonal tourism. Its small footprint will consume just one-quarter the space of traditional activated sludge biological processes, also making it easier to install in an underground bunker to hide from public view. The plant's modular configuration will enable it to achieve a biomass concentration of up to 10 g/L while eliminating the need for final sedimentation, filtration and disinfection treatment stages. The MBR system will also lower turbidity in the treated effluent; increase removal efficiency of organic matter, suspended solids and bacteria; and produce reuse-quality water that exceeds European Union standards.

The MBR system will contain four MBR filtration cells, each consisting of 224 hollow-fiber ultrafiltration membrane modules for a combined filtration surface area of 34,000 m². The pretreatment technologies will handle screening, compaction and washing of screened material, grit removal, and oil and grease removal.
