Area of Science:

  • Environmental Engineering
  • Chemical Engineering
  • Process Control

Background:

  • Water treatment unit operations are complex, non-linear, and not fully understood.
  • Existing process models are often unsuitable for control engineers.
  • Improving control and measurement in water treatment has yielded mixed results.

Purpose of the Study:

  • To investigate the application of feedback control for the clarification process in water treatment.
  • To maximize the efficiency of the chemical coagulation process using a streaming current detector (SCD).
  • To develop a simplified model of process operating conditions' impact on SCD measurements.

Main Methods:

  • Implementation of a feedback control system on a large-scale pilot plant.
  • Utilization of a streaming current detector (SCD) for real-time process measurement.
