A wastewater treatment plant (WWTP) is an environment high in nutrient concentration with diverse bacterial populations and can provide an ideal environment for the proliferation of mobile elements such as plasmids. WWTPs have also been identified as reservoirs for antibiotic resistance genes that are associated with human pathogens. The objectives of this study were to isolate and characterize...

In this work some multi-model and norm based approaches for Integrated Design of processes and constrained Model Predictive Control systems have been proposed. The Integrated Design procedure provides simultaneously the plant dimensions and working point together with the parameters of the control system by solving a multi-objective constrained non-linear optimization problem. Particularly, the...

Abstract Currently, the wastewater treatment plant (WWTP) for tofu industry in Ledok Kulon Village, Bojonegoro Regency uses an anaerobic-aerobic-anaerobic system. However, treated quality is still over maximum standard. To rectify this, objective of study was to technically improve WWTP so that could comply with required standards disposal into environment. This achieved without increasing capa...

The impact of effluent wastewaters from four different hospitals: a university (1456 beds), a general (350 beds), a pediatric (110 beds) and a maternity hospital (96 beds), which are conveyed to the same wastewater treatment plant (WWTP), was evaluated in the receiving urban wastewaters. The occurrence of 78 pharmaceuticals belonging to several therapeutic classes was assessed in hospital efflu...

This review paper focuses on modelling of wastewater treatment plants (WWTP). White-box modelling is widely applied in this field, with learning, design and process optimisation as the main applications. The introduction of the ASM model family by the IWA task group was of great importance, providing researchers and practitioners with a standardised set of basis models. This paper introduces th...

The prospection of bacteria that are resistant to polyaromatic hydrocarbons (PAH) activated sludge from a Petrochemical Wastewater Treatment Plant (WWTP) allows investigating potential biodegraders PAH. For this purpose, samples were cultured with benzo(a)pyrene and/or naphthalene as carbon sources. recovered isolates characterized by biochemical methods and identified based on the analysis seq...

Phosphorus is an essential nutrient for all living organisms. However, high concentrations in a water body accelerates eutrophication. Discharge limits for phosphorus are getting tighter for wastewater treatment plants, thus new tertiary treatments for removal have to be considered. In addition, hygienization of wastewater may become mandatory. At Viikinmäki wastewater treatment plant, the phos...

In this study, surface water samples from the Wenyu River and the North Canal, effluent from major wastewater treatment plants (WWTPs) in Beijing, and wastewater from open sewers that discharge directly into the river system were collected and analyzed for 16 priority USEPA polycyclic aromatic hydrocarbons (PAHs). Concentrations of these 16 PAHs ranged from 193 to 1790 ng/L in river surface wat...

This paper proposes a novel approach for the real-time monitoring of odour emissions from WasteWater Treatment Plant (WWTP) using an Instrumental Odour Monitoring System (IOMS). The plant is characterized by unpredictable peaks at its arrival tank (AT), generating nuisance and complaints in population living nearby plant. are most likely due to conferment non-identified malodorous wastewaters c...

Despite high performance, municipal wastewater treatment plants (WWTPs) still discharge significant amounts of organic material and nitrogen and even microbes into the receiving water bodies, altering physico-chemical conditions and microbial functions. In this study, we examined how nitrified wastewater affects the microbiology of boreal lake sediments. Microbial community compositions were as...
