    How often should I clean my membranes? In normal operation, the membrane in reverse osmosis membrane elements can become fouled by suspended solids, microorganisms and mineral scale. These deposits build up during operation and cause loss in water output or salt rejection, or both. Membrane elements should be cleaned whenever the normalized

    The multi-barrier approach is the best approach to reduce enteric viruses and other waterborne pathogens in drinking water. Since available analytical methods make it impractical to routinely monitor for microbial pathogens in treated drinking water, the focus should be on characterizing source water risks and ensuring that effective treatment barriers are in place to achieve safe drinking water.
