Abstract

Abstract: The aim of this paper is to describe the state-of-the art computer-based techniques for data analysis to improve operation of wastewater treatment plants. A comprehensive review of peer-reviewed papers shows that European researchers have led academic computer-based method development during the last two decades. The most cited techniques are artificial neural networks, principal component analysis, fuzzy logic, clustering, independent component analysis and partial least squares regression. Even though there has been progress on techniques related to the development of environmental decision support systems, knowledge discovery and management, the research sector is still far from delivering systems that smoothly integrate several types of knowledge and different methods of reasoning. Several limitations that currently prevent the application of computer-based techniques in practice are highlighted. Highlights: A review of computer-based techniques for wastewater treatment is conducted. EU has been leading this field. ANN, PCA, Fuzzy, Clustering, ICA and PLS are most cited techniques. Limitations exist that prevent the application of these techniques in practice.
