4 PagesBackground Free Chlorine Control It is well known that polyamide- based RO membranes are vulner- able to chlorine. Long-term expo- sure to trace chlorine can oxidize the membrane and compromise salt rejections. Commonly, sodium bisulfite (SBS, NaHSO 3 ) is used to neutralize the residual chlorine. The sulfite dosing rate required to neutralize the residual chlorine in feed water is calculated based on a stoichiometric mass balance and a
