The OPARA service was recently upgraded to a new technical platform. You are visiting the outdated OPARA website. Please use https://opara.zih.tu-dresden.de/ for new data submissions. Previously stored data will be migrated in near future and then the old version of OPARA will finally be shut down. Existing DOIs for data publications remain valid.
Batch test for measurement of biodegradable and inert COD fraction concentrations in municipal waste waters using UV-Vis senors
Abstract
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).
