To assess bioavailability levels and indentify important speciation for trace metals (Ni, Cu, Zn, and Pb), the rivers affected by a waste water treatment plant (WWTP) was studied. Biologically available concentrations were measured by the diffusive gradients in thin films (DGT) method, and DGT results were compared with those predicted by WHAM 7.0. At most sites downstream of the WWTP, bioavail...

Evolving Takagi-Sugeno (eTS) fuzzy models are used to build a computational model for the WasteWater Treatment Plant (WWTP) in a paper mill. The fuzzy rule base is constructed on-line from data using a recursive fuzzy clustering algorithm that develops the model structure and parameters. In order to avoid some redundancy in the fuzzy rule base mechanisms for merging membership functions and sim...

The concentrations and removal efficiencies of various kinds of micropollutants were investigated and the relationships between the input sources of industrial wastewater and occurrence patterns of each micropollutant were identified at nine on-site industrial wastewater treatment plants (WWTPs). The distribution pattern of each compound varied according to the WWTP type and several micropollut...

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 introduces DAI-Depur, an Environmental Decision Support System (EDSS). This systems supports the supervision of Municipal Waste Water Treatment Plants (WWTP). The paper highlights the succesful application of AI techniques to a complex environmental problem as the wastewater treatment that has both social and economic impact as well as in the environment. DAIDepur is successfully per...

Combined sewer overflows (CSOs) occur when flows exceed the hydraulic capacity of either the wastewater treatment plant (WWTP) or the collection system that transports the combined flow of storm water and sanitary sewage to the WWTP. When an overflow occurs, the excess flows tend to be discharged into a receiving body of water. CSOs typically discharge a variable mixture of raw sewage, industri...

Population growth and urbanization have led to the increasing presence of treated wastewater effluents in downstream drinking water sources. Drinking sources influenced by organic matter from upstream treatment plant (WWTP) are thought prone formation haloacetonitriles (HANs), a group nitrogenous disinfection by-products (DBPs) that can exhibit higher toxicity than currently regulated carbonace...

Tetracycline-resistant bacteria and genes encoding tetracycline resistance are common in anthropogenic environments. We studied how wastewater treatment affects the prevalence and concentration of two genes, tetA and tetB, that encode resistance to tetracycline. Using real-time polymerase chain reaction (PCR) we analysed wastewater samples collected monthly for one year at eight key-sites in a ...

The presented contribution reviews actual status of biogas production in the European countries with a focus on the Slovak municipal WWTPs. In 49 monitored Slovak WWTPs (out of 520) the anaerobic digestion with biogas production is operated. The total volume of digestion tanks is about 195 000 m3 but the total daily biogas production is only approx. 55 000 m3 d–1. From a technological point of ...

Many pathogenic bacteria are adapted to live in aquatic habitats, which makes rivers possible sources and spread pathways of antibiotic resistance, since they usually receive effluents from wastewater treatment plants (WWTP), possibly containing residues also antibiotic-resistant bacteria. This study investigates different monitoring strategies identify the occurrence rivers. We analyzed presen...
