The purpose of de-chlorination is the removal of free chlorine and combined chlorine compounds from potable water, as supplied by municipal water supplies. Chlorine will oxidize the surface of thin film composite polyamide membranes, causing the membrane to lose its ability to repel or reject salts. As a result, the membranes used in Reverse Osmosis (RO) or Electro-deionisation (EDI) systems will exhibit shorter lifetimes when exposed to chlorine in the water they are treating and membrane manufacturers will usually specify an upper limit to ensure a suitable life of the membrane. As a result, it is usual to use a method of dechlorination upstream of the RO or EDI system.
