Intelligent Techniques for Wastewater Treatment : A Technical Review
Abstract
Industrial wastewater treatment is a crucial but challenging task. The perpetual chemical and bio-chemical reactions impart a great deal of complexity to the composition of industrial wastewaters. While conventional modeling approaches can handle linear processes, complex systems exhibiting non-stationary behavior can prove challenging. Machine learning techniques based on variants of Artificial Neural Networks, Bayesian approaches and Genetic Algorithms have proven promising for outlier detection, model generation and prediction in the field of wastewater treatment. In this context, intelligent techniques enable both feature extraction and application of suitable algorithms to datasets to obtain precise results. Inference mechanisms that support decision-making combined with visualization render machine learning algorithms as the most dependable techniques for analyzing various factors affecting wastewater treatment systems. Machine learning approaches are useful for data processing, real-time modeling and actionable inference for compliance with government norms for wastewater treatment. Moreover, machine learning algorithms have also been applied in wastewater treatment to optimize efficiency parameters.
This paper reviews the application of machine learning algorithms for data processing, modeling, parameter optimization, prediction, and decision-making for efficient management of wastewater treatment processes. The challenges and limitations of these approaches are also discussed.
