This paper summarizes part of the research work carried out in the Add Control project, which proposes an extension of the wastewater treatment plant (WWTP) models and modelling architectures used in traditional WWTP simulation tools, addressing, in addition to the classical mass transformations (transport, physico-chemical phenomena, biological reactions), all the instrumentation, actuation an...

The paper describes linear and nonlinear modeling of the wastewater data for the performance evaluation of an up-flow anaerobic sludge blanket (UASB) reactor based wastewater treatment plant (WWTP). Partial least squares regression (PLSR), multivariate polynomial regression (MPR) and artificial neural networks (ANNs) modeling methods were applied to predict the levels of biochemical oxygen dema...

It has been previously demonstrated that vitellogenin (VTG)--a precursor egg yolk protein--is produced in male fish exposed to estrogenic compounds in wastewater treatment plant (WWTP) effluent. However, little attention has been given to examine whether any patterns of male VTG production exists across fish species on a global scale. We hypothesized that a composite measure of human population...

The aim of this project is to create an empirical model of a wastewater treatment plant (WWTP), which suits the requirements of integrated modelling. Such a model has to be simple enough in order not to increase too much the level of complexity and the computational demand when coupled with other submodels. The empirical model is identified using simulation data obtained from a mechanistic trea...

The data in this article mainly present the sequences of activated sludge from a full-scale municipal wastewater treatment plant (WWTP) carrying out simultaneous nitrogen and phosphorous removal in Beijing, China. Data include the operational conditions and performance, dominant microbes and taxonomic analysis in this WWTP, and function annotation results based on SEED, Clusters of Orthologous ...

This paper proposes the use of an auction process in which the capacity of a Waste Water Treatment Plant (WWTP) is sold to coordinate the industrial discharges. The main goal of coordination is to manage the wastewater inflow rate and pollutants to improve the WWTP operation. The system is modeled as a multi-agent system where each industry is represented by an agent, another agent represents t...

Currently, energy and environmental efficiency are critical aspects in wastewater treatment plants (WWTPs). In fact, WWTPs are significant energy consumers, especially in the active sludge process (ASP) for the N-ammonia removal. In this paper, we face the challenge of simultaneously improving the economic and environmental performance by using a reinforcement learning approach. This approach i...

Conventional wastewater treatment, primary and secondary treatment processes with simultaneous phosphorus precipitation, is the most common process combination used in Finnish wastewater treatment plants (WWTPs). It typically eliminates most of the organic load and phosphorus, as well as part of the enteric microorganisms present in raw wastewater. Municipal secondary effluents still contain so...

Industrial WWTP’s have to provide a 100 % reliability and availability for the discharging facilities (Bury et al., 2002). The industrial WWTP in this study treats wastewater the same way as most municipal WWTP, i.e. with an activated sludge process. However, some differences can be pointed out. The first problematic difference is that the composition of industrial wastewater fluctuates conside...

OBJECTIVE The goal of the current study was to gain insight into the prevalence and concentrations of antimicrobial resistant (AMR) Escherichia coli in Dutch surface water, and to explore the role of wastewater as AMR contamination source. METHODS The prevalence of AMR E. coli was determined in 113 surface water samples obtained from 30 different water bodies, and in 33 wastewater samples obt...
