How to calculate chlorine demand
WebChlorine does not provide better oxidation of manganese than oxygen at a pH < 9.5; however, these same filtration mixes can be used (pH ≥ 8) as catalysts when oxidising Mn 2+ using chlorine, occasionally after sedimentation and an initial filtration in an acid medium for the purpose of removing OM (case of some soft and coloured surface water). WebMinutes required = K / chlorine residual (mg/l) K values to determine chlorine contact time To calculate contact time, use the highest pH and lowest water temperature expected. For example, if the highest pH anticipated is 7.5 and the lowest water temperature is 42 °F, the "K" value (from the table above) using the formula is 15.
