Can the SCM be used to control coagulant dose to achieve removal of organics or colour?
The amount of dissolved material does not directly relate to streaming current. Therefore if the main reason for coagulant dosing is to remove organics, colour, taste and odour then a SCM will not be as helpful as it is for clay suspensions. However if there is both turbidity and dissolved material in the raw water then it can be beneficial to set the target SC to a slightly higher value than required for optimal turbidity removal.
