Ultrafiltration technology helps supply clean drinking water in Northern Portugal

Xylem has provided ultrafiltration solutions to the Santa Eufemia municipal water treatment plant, located in Northern Portugal, as part of a recent effort to expand the treatment capacity of the utility.

SCHAFFHAUSEN, SWITZERLAND, Sept. 22, 2014 -- Xylem Inc. (NYSE:XYL), a global water technology company aiming to address challenging water issues, has provided ultrafiltration solutions to the Santa Eufemia municipal water treatment plant, located in Northern Portugal, as part of a recent effort to expand the treatment capacity of the utility.

The facility, based north of the city of Oporto, has a new capacity of 24 million liters per day as a result of the upgrade, providing clean drinking water to roughly 80,000 people in the Guimarães and Vizela regions.

Xylem has worked with Moinhos Ambiente, the company in charge of engineering, procurement and construction for the project, to provide GE's ZeeWeed* 1500 membrane modules and Lowara pumps, as well as process and design engineering support, in a contract worth €430,000 ($552,500) to Xylem.

The Santa Eufemia plant treats water from the nearby Rio Ave River and is operated by Vimágua, the municipal authority for water management in the region. Plant upgrade work was required as a result of deteriorating water quality from the river. The plant is now one of the largest installations of GE's ZeeWeed 1500 modules in Europe and the Middle East.

Xylem has been a distribution partner for GE's membrane filtration products since November 2011. GE's ZeeWeed 1500 membranes were chosen for the Santa Eufemia plant because of their reliable filtration that provides superior water quality.

The ultrafiltration system provided by Xylem is designed with four parallel membrane trains, each incorporating 88 membrane modules. This ensures full system capacity and as it is fully automated, minimizes operator intervention.

The Santa Eufemia plant was originally constructed in the 1980s and performed with limited capacity since then. Vimágua decided to revamp the facility to install the ultrafiltration membrane plant following an in-depth study of alternative solutions.
