    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).
