The Streaming Current Meter provides a valuable tool for water treatment plant operators to optimize and control coagulant dosage. A major advantage of the SCM is that it
provides information at the beginning of the process. This measurement allows operators to know precisely if the coagulant dosage is at the optimum point. Alarms and control systems can enhance the use of the SCM. It is important that the instrument be installed and operated properly to receive the maximum benefit.
The SCM is an online instrument that continuously samples the treated water just after coagulant is added. Chemical coagulants are added to surface water to destabilize the
colloids and suspended material and promote flocculation. In raw untreated water, colloidal particles are stabilized with electrostatic forces. Oppositely charged chemicals reduce these repulsive forces to allow the particles to agglomerate or floc. The floc is then settled or filtered. The SCM
measures how well the chemicals are doing their job by detecting the residual charge in the sample. The measurement indicates if the surface charges have been neutralized. So anything that will affect the charge balance will affect the SCM reading.
