Abstract
Mathematical modelling of the activated sludge
process (ASP) enhances understanding of the process
and improves effluent quality. However, as the process
is complex and nonlinear, mathematical modelling has
been challenging. In this study, Random Forest
Regression (RFR) and Gradient Boosting Machine
regression (GBM) are investigated and compared to
predict biochemical oxygen demand (BOD), suspended
Solids (SS) and pH for better control of wastewater
treatment plants employing the activated sludge
process.
The study area selected was in a district of Kerala State
in India. The model is evaluated using correlation
coefficient R and the mean squared error (MSE). The
software Python 3.11 is used for modelling. It was
found that effluent BOD, SS and pH were predicted
with maximum correlation coefficients of 0.6778,
0.9157 and 0.7578 and mean square errors of 0.005,
0.006 and 0.0102 respectively, by RFR. GBM improves
the prediction of BOD, SS and pH, with correlation
coefficients of 0.7346, 0.974 and 0.8778 and mean
square errors of 0.0042, 0.0014 and 0.0051
respectively.
Mathematical modelling of the activated sludge
process (ASP) enhances the understanding of the
process and improves the quality of the effluent
released. However, as the process is complex and
nonlinear, mathematical modelling of the process has
been a challenge. In this study, multi-layer perceptron
artificial neural...

Anaerobic digestion (AD) is a key process for sludge treatment, volume reduction, and energy recovery in wastewater treatment plants (WWTPs). Therefore, the use of artificial intelligence methods in ED is recommended for better sludge and wastewater management. With the development of artificial intelligence, this...

Industrial effluents are a major source of water pollution, often leading to ecological imbalance and human health risks. Among these, paper mill effluent is particularly challenging to manage due to its high pollution load. This study aimed to evaluate the phytoremediation potential of Lemna minor for paper mill efflu...
