  • Biological filtration of poor quality brackish water reducing Reverse Osmosis membrane fouling

    Abstract A primary limitation in applying Reverse Osmosis (RO) is loss of performance caused by membrane fouling resulting from compounds that bacteria can use as energy or nutrient sources. When these compounds enter RO membranes, they are capable of sustaining extensive bacterial growths on the membrane sheets as well as within feed channel spacers. This leads to the entrapment of ...
