  • Reverse osmosis yield increased by 10% --- biocides reduced by 50%

    Fluid Dynamics is a world leader in  non chemical solutions for water treatment problems.. its non chemical hard water  scale prevention system Colloid-A-Tron  was recently installed in a Mitsui Chemicals plant in Thailand to protect RO membranes from fouling. The results were excellent .. the amount of pure water produced by  the membranes  increased by 10% .. ...

  • New Logic´s Vibrating Reverse Osmosis Membrane System Solves Leachate Treatment Problem at Ecuador´s El Inga Landfill

    New Logic Research announced today the successful commissioning of another VSEP vibrating membrane system at a municipal landfill – this time in Quito, Ecuador. The RO system takes landfill leachate from storage ponds and filters it to create clean water that is recycled and used as irrigation water. The water permeating from the system has only about 50 parts per million of dissolved ...

  • Thicker mesh spacer for 8 inch RO elements

    Starting July 1st Woongjin Chemical has standardized 32 mil mesh spacers for all its 8 inch (diameter) 40 inch spiral-wound RO elements (an increase from 28 mil). Also, optional 34 mil mesh spacers are available. Applying the new spacers will help save costs as it reduces the differential pressure. Fouling potential is also reduced because thicker mesh spacers creates more turbulence in the flow ...

  • 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 ...
