Control Strategy for Dissolved Oxygen of Paper Mill Activated Sludge Wastewater Treatment Process

Abstract

A fuzzy logic system combined with PID (Fuzzy-PID controller) to control the dissolved oxygen concentration in the paper mill wastewater treatment process is proposed based on the developed sequential batch reactor simulation model of the wastewater treatment process in paper mills. A case study with the presence of noise has been studied and evaluated with the criteria considered in Benchmark Simulation Model No. 1. The simulation results with white noise on the dissolved oxygen reveal that the Fuzzy-PID controller possesses better control indices than that of conventional PID controller. The good anti-interference ability of the Fuzzy-PID controller is meaningful and important for industrial application.
