Reverse Osmosis Membrane Cleaning

Having in normal operation for a period of time, the components of a reverse osmosis membrane can be polluted by the suspended matters or insoluble salts that may exist in water, the most common ones of these pollutants are calcium carbonate sediment, calcium sulfate sediment, metal (ferrum, manganese, copper, nickel, aluminum, etc) oxide sediments, silicon sediment, inorganic or organic sedimentary mixtures, NOM natural organic material, synthetic organic matters (for example, anti-sludging agent/dispersing agent, cationic polyelectrolyte), microbes (algae, mould, fungus), etc.

The pollution characters and speed are dependent on various factors, such as feed water properties and recycling rate of system. The development of a pollution is gradual, if control is not made as soon as possible, the membrane components can be damaged within a relatively short period of time by pollution. The cleaning on membrane components is suggested if it has been confirmed that the membrane components have been polluted, or before a long term shutdown, or as routine maintenance and repairs at fixed period.
