Analysis of water quality parameters and pharmaceutical trace substances for different solid fractions in a combined sewer.
(Technische Universität Dresden, 2022-09-16) Grüner, Stefan; Mayer, Robin Pascal; Krebs, Peter
The wastewater composition was determined at a combined sewer of the city of Dresden using in situ UV-Vis measurement technology, referenced by wet-chemical analysis of collected samples and additionally a determination of pharmaceutical trace substances was carried out. This data set was used for the publication of the doctoral thesis "Multiparameteranalyse und pharmazeutische Spurenstoffuntersuchung im Mischwasserkanal" of Stefan Grüner. (link: https://nbn-resolving.org/urn:nbn:de:bsz:14-qucosa2-793815). The aim of this work was to extend the system understanding of wastewater composition beyond the standard analytical parameters by using in situ UV-Vis measurement techniques, enhanced by the determination of pharmaceutical trace substances for different solid fractions.

Batch test for measurement of biodegradable and inert COD fraction concentrations in municipal waste waters using UV-Vis senors
(Technische Universität Dresden, 2023-04-19) Weber, Steffen; Mayer, Robin-Pascal; Krebs, Peter
In wastewater from the outflow of primary treatment (wastewater treatment plant, Dresden-Kaditz) and from a combined sewer of the city of Dresden, the wastewater composition was determined using in-situ UV-Vis measurement technology and oxygen consumption measurements combinded with the activated sludge model No.1 (ASM No. 1) and wet chemical analyzes from random samples as a reference. This data set was used for the publication of Steffen Weber's doctoral thesis "Fraktionierung des Chemischen Sauerstoffbedarfs mithilfe von Extinktionsmessungen im UV/Vis-Spektralbereich" by Steffen Weber. (link: https://nbn-resolving.org/urn:nbn:de:bsz:14-qucosa2-847298). The aim of this work was to extend the system understanding of the wastewater composition beyond the standard analysis parameters by using in situ UV-Vis measurement techniques to determine the COD components (fractionated according to ASM No.1).

Measuring the transformation of biodegradable and inert COD fraction concentrations along flow path in combined sewer system
(Technische Universität Dresden, 2023-04-12) Weber, Steffen; Mayer, Robin-Pascal; Krebs, Peter
In wastewater from a combined sewer of the city of Dresden, the wastewater composition was determined using in-situ UV-Vis measurement technology and wet chemical analyzes from random samples as a reference. In addition, the comparability of measurement results from identical spectrophotometer technology was checked. This data set was used for the publication of Steffen Weber's doctoral thesis "Fractionation of the chemical oxygen demand using absorbance measurements in the UV/Vis spectral range" by Steffen Weber (link: https://nbn-resolving.org/urn:nbn:de:bsz:14-qucosa2-847298). The aim of this work was to extend the system understanding of the wastewater composition beyond the standard analysis parameters by using in situ UV-Vis measurement techniques to determine the COD components (fractionated according to activated sludge model No.1).

Monitoring data to explore particle size distribution and elemental composition in a stormwater outlet from a German urban catchment
(Technische Universität Dresden, 2025-12-19) Benisch, Jakob; Rojas-Gómez , Karen L.; Helm, Björn; Borchardt, Dietrich; Krebs, Peter
This repository presents a dataset comprising online monitoring turbidity and discharge data measured with a high temporal resolution at the stormwater outlet of a small urban catchment in Dresden, Germany. Additionally, for selected rainfall-runoff events, the following data were produced: total suspended solids concentrations and their particle size distribution (<63 µm: fine particles; >63 µm: coarse fraction), their elemental composition and organic content. The online monitoring data covers January 2018 - August 2022, whereas the sampled data were collected during September 2018 - 2021. These data are optimal for exploring flush dynamics, transport patterns of particles and particle-bound pollutants, and for developing and validating particle transport formulations in urban drainage models. This will allow a better identification of stormwater treatment and management strategies to effectively address different pollutant flushes, to support regulatory decision-making, and to minimise the impact of stormwater discharges on the receiving water bodies.
