Plant Redesign for pH Neutralization Process of Textile Wastewater Treatment

Abstract

This study reports the redesign of a laboratory-scale pilot plant for textile wastewater treatment, especially in the pH neutralization process. The goal was to improve the plant structure, to facilitate more efficient process control. The result was a modular wastewater treatment plant that easy to operate and more efficient. A microcontroller controlled the plant. The plant was equipped with sensors and actuators to enable process monitoring and control in real-time. The control system was able to maintain the waste pH close to the setpoint (pH 8.5) despite the process disturbances.
