Online Streaming Current Detector SCD-6000


SCD-6000 Streaming Current Detector continuously measures ionic and colloidal charge, which indicates coagulant dosage in treated water. The SCD-6000 ensures optimum coagulant dosage. Excellent sensor design, to ensure that the instrument for a long time trouble-free operation, can save 20-30% of the cost of chemicals.
Benefits
  • Chemical Savings (20 - 35%)
  • Maintain Water Quality
  • Self calibrating and self monitoring
  • Feedback Control Easily Retrofitted
  • Optimize Treatment
Applications
  • Potable water treatment
  • Polymer control for sludge dewatering
  • Anionic trash detection in whitewater loops papermaking wet end processes
  • Power plants
  • Paper mills
  • Other applications requiring a chemical coagulation process

 Measuring Principle
The streaming current is one of the important electrical phenomena at the solid-liquid interface, which was first discovered in the capillary model test. When the liquid is subjected to a certain pressure through a capillary or microporous plug, charge transfer occurs during the liquid flow, and the current generated during this charge movement is called the streaming current. The potential difference at both pipe end is called the flow potential.
