“…ANN have been broadly investigated and applied in forecasting operational parameters in the drinking water treatment field, focusing mainly in the coagulation process (Baxter et al, 1999;Gagnon et al, 1997;Griffiths and Andrews, 2011;Juntunen et al, 2012;Maier et al, 2004) and on evaluating filter performance (Baxter et al, 2002;Hawari and Alnahhal, 2016). Other applications of ANN in similar environmental processes can be found in the literature regarding optimisation of metals and organic compounds sorption processes in the industrial water treatment field (Hamzaoui et al, 2017; Mazaheri et al, 2017). The great diversity of ANN that exists in the literature has led to the need of establishing frameworks and protocols in the last decade (Baxter et al, 2002;Humphrey et al, 2017;Maier et al, 2010;Wu et al, 2014) to homogenize criteria, avoid over-parametrization of ANN models and guarantee the reproducibility and scientific reporting of these models.…”
