Chlorine Demand

Effective disinfection relies on maintaining disinfectant residuals at levels which will inhibit or kill biofilms. To achieve suitable residuals in distribution systems with varying treated water qualities and retention times is not an easy task.

DCM can now simplify this task by proving continuous chlorine dosing set point adjustment. The s::can spectro::lyser in conjunction with DCM developed algorithms allows measurement of the levels of organics proven to react with chlorine and thereby remove it from the water. Note this does not take into consideration the effects of removals by biofims specific to a given distributor however it removes the variability inherent with water quality changes in the clear water leaving the WTP.
