Abstract

This paper demonstrates the evaluation of a rule-based control strategy for an equalization facility in front of an industrial wastewater treatment plant. The control goal is not only to dampen the flow rate but also the waste concentration and the load since its huge influence on the subsequent processes. This is complicated by the technical and financial constraints of the process. Overall, the equalization strategy consists of 32 rules in the basic configuration to which 25 rules are added to deal with the occurrence of pump failures that can be detected automatically. By means of simulation it was possible to evaluate the control performance. A 10-fold decrease of variance of flow rate, waste concentration and load was reached.
