In wastewater treatment plants, predicting influent water quality is important for energy management. The influent water quality is measured by metrics such as carbonaceous biochemical oxygen demand (CBOD), potential of hydrogen, and total suspended solid. In this paper, a data-driven approach for time-ahead prediction of CBOD is presented. Due to(More)
Total suspended solids (TSS) are a major pollutant that affects waterways all over the world. Predicting the values of TSS is of interest to quality control of wastewater processing. Due to infrequent measurements, time series data for TSS are constructed using influent flow rate and influent carbonaceous biochemical oxygen demand (CBOD). We investigated(More)
(16 km west of Oxford) and Iowa City (25 km east of Oxford). The computation results indicate that the three models offer similar accuracy when predicting rainfall at current time. Model II performs better than the other two models when predicting rainfall at future time horizons.
Sludge is a byproduct of wastewater processing suitable for biogas production. The biogas consisting of about 60% methane can be used to generate electricity and heat. A data-driven approach for optimization of biogas production process in a wastewater treatment plant is presented. The process model is developed using routinely collected data categorized as(More)
A data-driven approach for maximization of methane production in a wastewater treatment plant is presented. Industrial data collected on a daily basis was used to build the model. Temperature, total solids, volatile solids, detention time and pH value were selected as parameters for the model construction. First, a prediction model of methane production was(More)

Wastewater pumping consumes 10% to 20% of electricity in wastewater treatment plants. To reduce the energy consumption, a data-driven approach is applied to model and optimize the wastewater pumping process. Data-mining algorithm and multilayer perceptron neural network are used to build the pumping energy model. The optimization model is solved by an(More)
