Abstract

Ozone is known to be a powerful oxidant and disinfectant in drinking water production processes. The ozone dosing process presents a particularly difficult control problem due to its nonlinear behavior. Most water treatment plants use ozone dosing by determining the ozone concentration based on operational experience without considering temporal variations in water quantity and quality. In this case, this approach can lead to an overdosing that can increase costs or an underdosing that will influence the quality of the treated water. Two deep learning models, namely, the DNN model and CNN model, were applied for ozone dosing predictive modeling tasks. Comparing the results obtained in the training and testing processes, we notice that the DNN model with 5 hidden layers outperforms the CNN model. These results seem very encouraging, and the methodologies seem promising.
