GE powers largest drinking water treatment plant in Europe

Greentech Lead Europe: GE now provides technology to the largest drinking water purification plant in Europe.

The ZeeWeed 500 advanced water treatment technology is under construction in Ravenna, Italy.

Several years ago, Romagna Acque – Società delle Fonti SpA, the public company in charge of the water wholesale supply for Italy’s Romagna region, realized it needed to heavily invest in supplementing its existing water supply to ensure water always is available.

The municipality selected GE’s membrane technology for the project due to its ability to convert deteriorated raw source water into high-quality, safe drinking water. GE ZeeWeed 500 technology separates particles, bacteria and viruses from water or wastewater. Nearly 1,000 plants worldwide use this technology to produce superior quality.

Often plagued by long periods of drought that cause the reservoirs to reach critically low levels, the region turns to the Po River, the longest river in Italy, as a drinking water source. The raw water from the Po River has a high variation of solids and turbidity especially after rain, and the new drinking water plant needed a reliable method to purify the severely deteriorated incoming water.

“Our region’s economy depends on industrial assets and on seasonal tourists who come to Ravenna’s coastal area for popular beaches and historical sites. Safe and reliable drinking water is essential to ensuring visitors continue to patronize the Romagna region,” said Andrea Gambi, CEO, Romagna Acque – Società delle Fonti SpA. “We had been experiencing water shortages and needed to add to our reliable supply of water. Building a new drinking water plant with GE’s ZeeWeed technology is the key to turning the river into a safe and dependable source of potable water.”

Once operational, the new drinking water plant utilizing GE’s ZeeWeed 500 technology will treat an average flow of 95 million liters per day (MLD), which is enough water to serve approximately 400,000 people.

GE will provide the technology to the engineering, procurement and construction joint venture led by Torricelli S.r.l., in partnership with Degrémont SpA. Featuring 40 cassettes filled with ZeeWeed 500 modules and distributed in eight filtration trains, the new facility will be the largest potable plant of its kind in Europe using GE technology.
