  • 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 ...

  • Global RO Membrane Market to Grow at 7% CAGR to 2019

    Reverse Osmosis is a technology that uses a semi-permeable membrane to remove dissolved salts or organic molecules. The water is pushed under pressure through the membrane, which allows the passage of water molecules but prevents the dissolved salts and bacteria to pass through. A high-pressure pump is used to apply the required pressure for carrying out the process, and depends on the salt ...
