Italian wastewater treatment plant upgrades with GE ZeeWeed technology

GE supplied Servizi Ambientali SpA with MBR technology and equipment featuring ZeeWeed 500D reinforced, hollow-fiber membranes. The upgrade included four ZeeWeed 500D trains, 24 cassettes and 1152 modules.

The membrane plant, which is located on the seacoast and discharges into a sensitive ecosystem in a tourist region, was built three years ago to initially treat 7 million liters per day (MLD) or 7000 m3/d. With the new expansion, using GE ZeeWeed technology, the wastewater treatment plant quadruples the flow and serves approximately 140 000 residents in the towns of Borghetto Santo Spirito, Loano, Toirano, Boissano, Balestrino and Ceriale in Italy’s Liguria region.

“Governments and municipalities continue to look for ways to properly treat wastewater and possibly reuse it for non-potable purposes, particularly in highly tourist regions such as Loano and Liguria. Discharging effluents with high quality characteristics obtained through ultrafiltration technologies, such as GE’s ZeeWeed, is essential to preserve the environment,” said Jeff Connelly, vice president, engineered systems - water and process technologies for GE Power & Water.
