Control strategy designs and simulations for a biological waste water treatment process
*Subscription may be required
A new and more appropriate continuous recycled system for aBiological Nutrient Removal process has been developed based on a sequencing batch reactor. This system comprises a Continuously Stirred Tank Reactor, a surge tank and a settling tank, from which a fraction of treated water is recycled back to the reactor. To design the control system for the whole plant, step tests have been conducted and Relative Gain Array analysis performed. Six control loops with the Process Variables including dissolved oxygen and nitrate concentrations, and volume holdups have been formed. Two designed control strategies Proportional Integral controllers and Generic Model Control have been implemented. The simulated results will be presented for comparison.
