The inactivation of antibiotic resistant bacteria (ARB) and genes (ARGs) in an advanced plant combining ozonation granular activated carbon (GAC) filtration applied for effluent after conventional sludge treatment at a full-scale urban wastewater was investigated over 13 consecutive months. nitrite compensated specific ozone dose ranged between 0.4 0.7 g O3/g DOC with short-time sampling campaigns (0.2-0.9 DOC). Samples were analysed culture-dependent methods bacterial targets qPCR genes....
Lactic acid can be derived from microbial fermentation and used as a platform chemical in various industrial applications. This study aims to investigate the challenges involved combining low-cost, heterogeneous feedstock, such mixture of candy-waste digestate, with an optimized downstream strategy achieve maximum recovery high-purity lactic acid, targeting low energy consumption. To this goal, four membrane separation technologies, namely microfiltration, nanofiltration, monopolar, bipolar...
In this study, the effectiveness of a novel adsorbent/precipitant containing powdered activated carbon (PAC) and poly aluminum chloride (PACl) was evaluated for simultaneous removal organic micropollutants (OMP) phosphorus. Results showed better performance with prototype suspension at similar PAC/DOC doses, possibly due to changes in surface chemistry caused by PAC's acid precipitant. Further lab tests wastewater treatment plant (WWTP) effluent samples confirmed prototype's different...
Electrodialysis (ED) is a promising technology suitable for nutrient recovery from wide variety of liquid waste streams. For optimal operating conditions, the limiting current density (LCD) has to be determined separately each treated feed and ED equipment. LCD most frequently assessed in NaCl solutions. In this paper, five graphical methods available literature were reviewed determination series solutions with different levels complexity ion matrix composition. Wastewater microbial...
In this study, we i) assessed the occurrence of perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) in sediments, pore water, bulk water from three different areas Lake Neusiedl, Austria, ii) investigated mechanisms regulating adsorption remobilization these substances under conditions via multiple lab-scale experiments. The capacity was mainly influenced by sediments' organic matter content, oxide composition, pre-loading. Results suggest that a further increase...
The loading of granular activated carbon (GAC) is influenced by the amount water treated and concentrations adsorbates present in matrix. Through extraction experiments, we aimed to investigate total adsorbed mass eight organic micropollutants using ethanol as solvent maximum possible concentrations, due desorption micropollutants, water. Three different drying methods impact contact time, GAC particle size, GAC/solvent ratio were investigated. Although no significant differences between...
A set of CALUX in vitro bioassays was applied for long-term toxicity monitoring at an advanced wastewater treatment plant comprising ozonation and granular activated carbon filtration the abatement contaminants emerging concern (CEC). During 13-month monitoring, eight reporter gene assays targeting different modes action along cellular pathway were accessed to evaluate suitability robustness technologies. Two approaches followed: on one hand, signal reduction during monitored; other results...
Zusammenfassung In der vorliegenden Studie wurde die Wirksamkeit einer Adsorptions‑/Fällmittel-Prototypsuspension Firma Donau Chemie AG zur simultanen Entfernung von Spurenstoffen und Phosphor aus kommunalem Abwasser untersucht. Die Suspension enthält Polyaluminiumchlorid Fällung gelöstem Orthophosphat, Pulveraktivkohle (PAK) Adsorption organischen sowie anorganische Stabilisatoren, PAK unterstützen. Vergleichende Laborversuche mit herkömmlicher Prototypsuspension einem PAK-Gehalt 16,5 %...
Zusammenfassung Im vorliegenden Artikel wird auf Basis unterschiedlicher Datenquellen in einem ersten Schritt die Belastung des Neusiedler Sees mit national oder gemeinschaftlich geregelten anthropogenen Spurenstoffen dargestellt. Darüber hinaus werden für ausgewählte Stoffe Eintragspfade Wulka und See identifiziert weitere ein mögliches Umweltverhalten im Auch wenn derzeit umfassendes Monitoring von allen fehlt, kann den überwiegenden Teil dieser Untersuchungen der bzw. Fischuntersuchungen...
In this study, an amplicon metagenomic approach was used to determine the effect of repeated treatments with ozonized oleic acid on microbial community grapevine carpoplane. Differences in composition treated vineyards were compared non-treated and conventionally samples regarding prokaryotic eukaryotic microbiome at two developmental stages (BBCH 83, BBCH 87). The results showed effects both occurrence abundance microorganisms assembly. Wine-relevant genera such as Acetobacter members...
<p>Lake Neusiedl is the largest endorheic lake in Central Europe, straddling Austrian–Hungarian border. The has an area of 315 km<sup>2</sup>, 52% which covered by a reed belt representing second contiguous population Europe. lake's drainage basin about 1,120 km<sup>2</sup> and strongly impacted intensive agricultural production urban settlements, especially catchment main inflow River Wulka. On average,...

Historical experience shows that wood-pastures provide high habitat diversity and thus also a degree of species diversity, as such they have been under discussion for some years conservation measure. However, the development vegetation various groups animals on newly grazed is only poorly understood. Comparative approaches, exclosure certain areas, are required an evaluation these developments from nature perspective. By fencing off wood-pasture which had used by heck cattle six we were able...
