A Systematic Survey on the Research of AI-predictive Models for Wastewater Treatment Processes

Abstract

Context: To increase the efficiency of wastewater treatment, modeling and optimization of pollutant removal processes are the best solutions. The relationship between input and output parameters in wastewater treatment processes (WWTP) are the complicated one, and it is difficult for designing of models using statistics. Artificial Intelligence (AI) models are generally more flexible when comparing with statistical models while modeling complex datasets with nonlinearity and missing data. Objective: Studies on WWTP of AI based are increasing day by day. Therefore, it is crucial to systematically review the AI techniques available which are implemented for WWTP. Such kind of review helps for classifying the techniques that are invented and helps to identify challenges as well as gaps for future studies. Lastly, can sort out the best AI technique to design predictive models for WWTP. Method: With the help of the most relevant digital libraries, the total number of papers collected are 1222 which are based on AI modelling on WWTP. Then the filtration of the papers is mainly based on the inclusion and exclusion criteria. Also, to identify new relevant papers, snowballing is the other technique applied. Results: Finally selected 76 primary papers to reach the result that were published between 2004 and 2020. Conclusion: ANN with MLP approach on BP algorithm become a supervised neural network called BPNN is the most used AI modelling for WWTP and around 40% of the experimental research done with BPNN. Then there are some limitations on AI modelling of WWTP using photoreforming which is the current study of WWTP represents a promising path for generating renewable and sustainable energy resources like chemicals and fuels.

“…However, this is just one of the many instances of how technology is transforming people's lives. Artificial intelligence (AI) is rapidly growing [27][28][29][30][31][32], and innovations such as ChatGPT platform support people in writing, programming, and developing applications with greater ease and efficiency [33][34][35][36][37][38][39][40]. Self-driving cars, also known as autonomous vehicles, are another breakthrough that promises to revolutionize the way we travel and commute.…”
