Dow Water & Process Solutions reinforces commitment to R&D with successful piloting of DOW Ultrafiltration Modules

Dow Water & Process Solutions is demonstrating its dedication to research and development (R&D) through investment in progressive product piloting. As part of this continued research, the company has announced the results of a recent piloting focused on DOW Ultrafiltration technologies, which was carried out at its Global Water Technology Center in Tarragona, Spain.

The pilot program aimed to monitor the quality of the feedwater produced by the DOW Ultrafiltration system, in order to provide support for Dow Water & Process Solutions’ wide range of Ultrafiltration technologies, reinforces its ongoing dedication to R&D and improvement of its products and solutions. The results of piloting confirm the sustainable and stable operation of DOW Ultrafiltration commercial modules as a pre-treatment for the Reverse Osmosis system downstream for more than 300 accumulated days, demonstrating their robustness in a real wastewater reuse application with relatively high organic content.

In order to provide real wastewater conditions, the pilot system was fed with secondary effluent from the Vilaseca (Tarragona, Spain) municipal wastewater treatment plant. Typically, due to wastewater feed quality and characteristics, the Reverse Osmosis system cannot be fed directly from the secondary effluent of the wastewater treatment plant without interruption. Therefore, to guarantee the required feed quality to the Reverse Osmosis system, a DOW Ultrafiltration SFP-2880 system was integrated upstream.

Alexander Lane, EMEA Commercial Director, Dow Water & Process Solutions, says, “We are committed to investing in research and development to ensure the highest quality and efficiency of our products, not only in Spain and Europe, but across the globe.”

DOW Ultrafiltration modules stand out for their hydrophilic PVDF hollow fibers, which feature high strength, chemical resistance and low-fouling tendency, as well as their optimized flow configuration (OUT-IN) for high tolerance to a wide variety of feed water types, minimizing the risk of fiber plugging.
