  • A New Way to Determine Fouling

    A new ASTM test method serves as an important option in determining the potential of particulate matter to cause fouling in pressure-driven membrane processes used in water treatment. ASTM members say that this new alternative (soon to be published as D8002, Test Method for Modified Fouling Index (MFI-0.45) of Water) will help end the struggle to entirely change an existing test method (D4189, ...

  • Breakthrough in prefiltration that protects RO membranes

    Dr. Ibrahim El-Azizi, of the University of Sheffield, recently presented a paper at a desalination conference in Amman Jordan, focusing on the causes of fouling of reverse osmosis (RO) membranes. In a pilot test of filters at a desalination plant in Libya, he studied the causes and extent of fouling. He concluded that filters using “Disruptor™ media is the best solution for reducing the fouling ...
