    Abstract The performance of electrocoagulation-flotation (ECF) process can profoundly be affected by the reactor design and electrode configuration. These may, in turn, influence the removal efficiency, flow hydrodynamic, floc formation, and flotation/settling characteristics. The present work aimed at developing a new spiral electrode configuration to enhance the ECF process. To do so, the impacts of parameters such as energy consumption, removal efficiency of the contaminants from industrial wastewater with a composition of turbidity, emulsified oil, and heavy metals (Si, Zn, Pb, Ni, Cu, Cr, and Cd), as well as stirring speed and foaming have been investigated. Comparison was also made between the experimental results of the new electrode configuration with the conventional rectangular cell with plate electrode configuration with the same volume and electrode surface area. The findings revealed that energy consumption of the spiral electrode configuration within the operating times of 10, 20, 30, 32, 48, and 70 min, was approximately 20% lower compared to that of the conventional ECF. Moreover, the maximum and minimum removal efficiency of 97% and 60% were obtained for turbidity and TOC for the stirring speed of 500 rpm and Reynolds number of 10,035, respectively. Finally, the formed gas bubbles tilted toward the center due to the enhanced flow hydrodynamic which resulted in substantial reduction of foam formation.

    Abstract This paper includes a comprehensive literature review of sludge composition data from wastewater treatment plants. 722 data sets from 249 sources were used to establish typical ratios between COD and solids-based parameters and to verify rule-of-thumb values, respectively. Confirmation of these typical ratios can also be accomplished by using biochemical composition data. It is shown that a correlation between data from proteins, lipids and carbohydrates analysis can be related to COD/VSS ratios. Finally, using the findings from the literature review, the organic and inorganic conversion factors of COD fractions in activated sludge models are adjusted to solids-based parameters. It was shown that with the adjustments of the factors and a partition of the particulate inert fraction into a fraction assigned to the influent and a fraction assigned to the endogenous products, a better agreement with the ratios of COD/VSS in the individual sludge streams can be established.

    Abstract Dieses von Mitgliedern des Arbeitskreises "Postwachstumsökonomien" (2016 - 2020) der ARL verfasste Positionspapier ordnet die internationale Postwachstumsdebatte ein und diskutiert ihre Relevanz für die Raumentwicklung und die raumwissenschaftliche Forschung. Neben sektoralen Zugängen und Befunden werden konkrete Vorschläge zur Postwachstumsorientierung in Planung, Forschung und Lehre gemacht. Dabei wird zwischen kurzfristig erreichbaren Veränderungen und mittel- bis langfristig auszulegenden Maßnahmen unterschieden.

    Abstract Auf Grund mehrjaehriger Erfahrungen bei der Nassanalytik von Abwasser- und Sickerwasserproben sollten Vor- und Nachteile der unterschiedlichen Methoden bei der Bestimmung der Parameter CSB, TKN, Gesamt-Phosphor und organische Saeuren dargestellt werden. Gleichzeitig wird auf Fehlerquellen, die waehrend der Abwasseruntersuchungen auftraten, hingewiesen und ein Zeit- und Kostenvergleich angestellt. Bei der Betrachtung aller angewandter Verfahren ist festzustellen, dass besonders bei homogenisierten Proben mit den Kuevettentests erhebliche Fehler auftreten. Dies liegt an der geforderten sehr kleinen Probenmenge. Fuer filtrierte Proben stellen diese Tests eine gute zeitsparende Alternative dar. Bei der Bestimmung des Gesamtstickstoffs im Abwasser ist von den LATON-Tests der Firma Dr. Lange abzuraten, da diese sehr fehlerbehaftet sind.
