Streaming Current Monitors & Detectors – StreamerSense

Streaming Current Monitors and Streaming Current Detectors from Pi use streaming current measurement (similar to Zeta Potential) to maintain proper electrokinetic charge (ionic & colloidal) in coagulation control applications in water treatment. Effectively these coagulation analyzers detect and control the level of residual coagulant. The objective is to keep this residual at a minimum while maintaining desired final water quality and process efficiency. The Streaming Current Monitor can be used as an effective feedback coagulation control tool allowing the operator to optimize the coagulation dose, effectively building a coagulation analyzer.

The coagulation analyzer uses streaming current measurement to maintain proper electrokinetic charge (ionic & colloidal) in the treated water. Effectively, it responds to changes in raw water characteristics (turbidity, color, pH, etc.) and flow rates. This allows the operator, or an automated control device, to make the necessary coagulant feed adjustments in order to continuously maintain the optimum dosage. In some water treatment facilities the water chemistry is such that the coagulation analyzer on its own is insufficient to properly control coagulation and in these applications the coagulation analyzer (streaming current monitor) can be enhanced with UV254 measurement, turbidity measurement and pH measurement to create a multi-sensor coagulation control system.
