Unravelling key factors controlling vivianite formation during anaerobic digestion of waste activated sludge

As a product of phosphorous recovery from anaerobic digestion (AD) of waste activated sludge (WAS), vivianite has received increasing attention. However, key factors controlling vivianite formation have not yet been fully addressed. Thus, this study was initiated to ascertain key factors controlling vivianite formation. A simulation of...

The negative effect of carbohydrates on protein degradation in the acid-phase of anaerobic digestion of protein-rich wastewater: a microbial composition study

Anaerobic digestion (AD) is a promising technology to process protein-rich wastewater. However, incomplete protein degradation during the acidification of organic matter is frequently observed when carbohydrates are present. Literature reports little information to explain the mechanisms behind this phenomenon. This MSc study investigated the...

Influence of particle size distribution on anaerobic degradation of phenol and analysis of methanogenic microbial community

Sludge morphology considerably affects the mechanism underlying microbial anaerobic degradation of phenol. Here, we assessed the phenol degradation rate, specific methanogenic activity, electron transport activity, coenzyme F₄₂₀ concentration, and microbial community structure of five phenol-degrading sludge of varying particle...
