Design and implementation of an integrated training and decision support system for the activated sludge process.

Abstract

In North America, the activated sludge process is commonly used in wastewater treatment. However, there are many aspects of the process that elude researchers, in particular, those that will ensure a successful control and optimization of the process. Because of the biological nature of the activated sludge process, its characteristics are highly dependent on environmental factors and hence can be very difficult to control and manage successfully. A very important factor contributing to an optimized activated sludge plant is the experience of its operators with the activated sludge process. This is achieved through the use of a variety of tools including traditional classroom training, computer based training, expert systems and simulation tools. Some of the tools aim to help the new operators acquire this experience quicker while others aim to enhance the experience of seasoned operators. This project presents a premise that an integration of these tools will be an effective and innovative way to help the operators achieve their goals. Hence, a design of an Integrated Training and Decision Support System (IT-DSS) has been proposed, and parts of the prototype system have been built. Preliminary results showed that such an integrated solution is feasible and realisable although a fully functional system has yet to be realised due to the scope limit. The results of this project provided solid and valuable starting points for the completion of such a step, and they also further support the value of the integration approach that has been put forth.
