In management of helminth infections and transmission, the correct prediction of sludge accumulation patterns in waste stabilization ponds (WSP) is important as sedimented eggs are associated with sludge depth. However, sedimentation in WSP is complicated ...
New-generation bioprocesses using granular sludge aim for a high-rate removal of nutrients from wastewater with low footprint. Achieving enhanced biological phosphorus removal (EBPR) relies on the design of sludge beds and wastewater feeding conditions to ...
Halogenated organic compounds (so-called organohalides) represent one of the major widespread groundwater pollutants. Organohalide respiration (OHR) is a bacterial anaerobic process in which chlorinated compound, e.g. tetrachloroethene (PCE), is used as te ...
Given the great concern about phosphorus (P) resource depletion, it's promising to recover P from waste activated sludge (WAS) especially for agricultural application. To this end, it's necessary to understand the P speciation and fractionation within the ...
Municipal water/wastewater agencies play an essential role in community well-being. Traditionally, municipal water/wastewater agencies have followed a linear (“take, make, dispose“) mode of thinking based on resource extraction. Often, the model follows th ...
The animal husbandry sector is a large contributor to greenhouse gas (GHG) emissions, particularly the emissions of methane and nitrous oxide. It is possible to reduce these emissions through better livestock management, composting of animal manure or turn ...

The present doctoral thesis aimed to achieve a robust cultivation of microalgae by recycling nitrogen from a liquid digestate. However, the use of non-sterile nutrient source increases the risks of contamination of undesired organisms such as bacteria, vir ...
Questions: What is the impact of nitrogen (N) inputs on the vegetation of mountain permanent grasslands? Beyond the effect of fertilizer quantity (total and available N supply), is there a specific effect of fertilizer quality (the various N sources) on th ...
Abstract The genus Dehalobacter embraces bacterial populations that seem to exclusively degrade organohalides. All isolates in pure culture and highly enriched strains are obligate organohalide-respiring bacteria that use hydrogen as energy and electron so ...
With 6% of Europe's freshwater resources, Switzerland is often considered the ‘water tower of Europe’. Over 8 millions residents rely on more than 57’600 farms to provide meat, milk, or eggs, with 1.58 million cattle, 1.58 million swine or 9.39 million pou ...
