Abstract

An Aquatic Quality Automation System (AQAS) is a system designed to monitor and control the water quality. This system usually installed at the wastewater treatment plant. Raw waters, such as water from river usually have a low pH value, which can be group as acid. This system is trying to neutralize the pH value as to make the pH value as close to 7 as possible. In this project, a controller for this system will be designed. The controller will be designed to monitor and control the pH of the liquid in a Continuous Stirred Tank Reactor (CSTR). pH control system is well-known as a difficult process due to the nonlinearity of the titration curve of the pH itself. In this project, a good controller will be designed to overcome the non-linearity of the pH control system. pH value can varies significantly during neutralization process. The controller designed must be set up at a typical specification and able to react accordingly to the changes in pH during the whole process. PID controller will be designed for this project. SIMULINK software will be use in this project to aid in the controller design stage. It is concluded that using the PID controller can actually be use for pH control system. The SIMULINK software is a great help during the designing and simulation stage as to optimize the PID controller.
