"At Pentair, we believe that the health of our world depends on reliable access to clean water. Our focus is on developing smart, sustainable water solutions-enabling people, communities and industry to access clean, safe water, reduce water consumption, and recover and reuse it," said Phil Rolchigo, Ph.D., Chief Technology Officer, Pentair. "Our work on the Keppel Marina East Desalination Plant demonstrates how Pentair's technologies can help address water challenges, and we are proud to be the technology partner to Keppel Infrastructure and PUB, Singapore's national water agency, on this endeavor."

Once completed in 2020, the 30 million gallon per day (mgd) Keppel Marina East Desalination Plant (KMEDP) will be Singapore's fourth desalination plant and the first large-scale dual-mode desalination plant, able to treat either seawater or freshwater from the Marina Reservoir. Pentair contributes with engineering services, Pentair X-Flow ultrafiltration (UF) membranes, Pentair Codeline pressure vessels, and a Pentair Haffmans/Union carbon dioxide (CO2) injection system for this project.

With 721 square kilometres (km2) of land and 5.6 million people, Singapore is among the most densely populated countries on Earth. The country's water resources are derived from its "Four National Taps" - local water catchments, imported water, high-grade, ultra-clean reclaimed water known as NEWater, and desalinated water.  

The Keppel Marina East Desalination Plant (KMEDP) is being built by Marina East Water Pte. Ltd., a wholly-owned subsidiary of Keppel Infrastructure Holdings Pte. Ltd. under a 25-year Design, Build, Own and Operate (DBOO) arrangement. The desalination plant is located in the scenic Marina Bay area with many famous landmarks such as the Marina Bay Sands, Gardens by the Bay and Marina Barrage in its backdrop. When completed, the KMEDP will present many "firsts" for Singapore. For a start, the KMEDP will be the first desalination plant located in the city, harmonizing seamlessly with the surrounding parkland for the enjoyment of the public and maximizing land use in land-scarce Singapore. The KMEDP will also be the first dual-mode desalination plant to be built in Singapore utilizing either seawater or freshwater from Marina Reservoir as its feed.

The KMEDP will also be the first large-scale desalination plant in Singapore to use the Direct-Coupling UF-RO (reverse osmosis) approach in its process design where the filtrate from the UF pre-treatment is fed directly to the downstream RO process. This design eliminates the need for a RO break tank and a pumping stage for the RO, resulting in significant cost, space and energy savings. Pentair is proud to be a technology partner to Keppel and PUB in the KMEDP project, supplying its Seaguard Ultrafiltration membranes for the plant and sharing its expertise in direct-coupling desalination operations.
