Ensuring the performance of wastewater treatment processes is important to guarantee that the final treated wastewater quality is safe for reuse. However, bacterial concentration present along the different stages of treatment process is not easily measured routinely for the plant operators. A moving horizon sensing approach based on neural networks has been proposed in [1] for measuring the bacteria concentration from easy to measure variables. The obtained model has been successfully tested on KAUST wastewater plant. In this project, the student will test and extend the model to other sets of data. A particular interest will be on incorporating self-calibration or self-training strategies to guarantee good performance of the proposed algorithm.
