Results obtained in a study using the Benchmark Simulation Model No. 1 (BSM1) show that a one-dimensional secondary settling tank (1-D SST) model structure and its parameters are among the most significant sources of uncertainty in wastewater treatment plant (WWTP) simulations [Ramin et al., 2011]. The sensitivity results consistently indicate that the prediction of sludge production is most se...

An assessment of the concentrations of thirteen different therapeutic pharmaceutical compounds was conducted on water samples obtained from different wastewater treatment plants (WWTPs) using solid phase extraction and high- and ultra-high-performance liquid chromatography with mass spectrometry detection (HPLC-MS/MS and UHPLC-MS/MS), was carried out. The target compounds included ketoprofen an...

Rural wastewater treatment plants (WWTP) are recognized as a significant phosphorous (P)-emission source in the German sub-catchments of the Baltic Sea. But enhancement of P-removal is cost intensive especially for small communities. This study proposes a concept to efficiently reduce P-emissions from WWTP by introducing low-cost non-constructional measures and assessing the resulting change of...

BACKGROUND Antibiotics have been increasingly used for veterinary and medical purposes. The overuse of these compounds for these purposes can pollute the environment, water resources in particular. Tetracycline, among other forms of antibiotics, is one of the most applied antibiotic in aquaculture and veterinary medicine. The present study aimed to tack the traces of tetracycline in the effluen...

THIS STUDY WAS INITIATED TO EXPLORE THE EMISSION CHARACTERISTICS OF REDUCED SULFUR COMPOUNDS (RSCS: hydrogen sulfide, methyl mercaptan, dimethyl sulfide, dimethyl disulfide), ammonia and trimethylamine from a Wastewater Treatment Plant (WWTP) located at Sun-Cheon, Chonlanam-Do in South Korea. The study also evaluates flux profiles of the six selected odorous compounds and their flux rates (μg/m...

Bacterial metabolism determines the effectiveness of biological treatment of wastewater. Therefore, it is important to define the relations between the species structure and the performance of full-scale installations. Although there is much laboratory data on microbial consortia, our understanding of dependencies between the microbial structure and operational parameters of full-scale wastewat...

Antibiotic resistance (AR) is a growing health concern worldwide, and the Arctic represents an understudied region in terms of AR. This study aimed to quantify AR genes from effluent released wastewater treatment plant (WWTP) Iqaluit, Nunavut, Canada, thus creating baseline reference for future evaluations. Water, sediment, truncate softshell clam (Mya truncata) tissue samples were compared was...

Abstract. Anelia N, Suhartono S, Hayati Z. 2023. Abundance and phenotypic-genotypic analysis of antibiotic-resistant Escherichia coli isolated from wastewater the Zainoel Abidin Hospital, Banda Aceh, Indonesia. Biodiversitas 24: 2294-2301. Excessive inappropriate use antibiotics can initiate emergence antibiotic resistance in bacteria. Wastewater Treatment Plant (WWTP) is believed to be a reser...

Planning for a communal scale Wastewater Treatment Plant (WWTP) in Depok Village, Trenggalek Regency, East Java is needed because most of the wastewater Village only treated with septic tanks. This study aims to plan WWTP design based on generation domestic and non-domestic Village. The planning this was carried out results laboratory test parameters pH, TSS, BOD, COD, total coliform, fatty oil...

This paper describes the combination of Multivariate Statistical Process Control (MSPC) and Case-Based Reasoning to situation assessment of a Waste Water Treatment Plant (WWTP). The goal of this work is to evaluate the capabilities of these techniques for assessing the actual state of a WWTP. The research was performed in a pilot WWTP operating with a Sequencing Batch Reactor (SBR). The results...
