Biological phosphorus removal during high-rate, low-temperature, anaerobic digestion of wastewater
(Frontiers Media, 2016-03-03)We report, for the first time, extensive biologically mediated phosphate removal from wastewater during high-rate anaerobic digestion (AD). A hybrid sludge bed/fixed-film (packed pumice stone) reactor was employed for ... -
Food waste fermentation for lactic acid production and recovery
(NUI Galway, 2022-09-23)This research aimed at optimizing the lactic acid production process exploiting the organic matter present in food waste. The objective was to investigate every aspect of the industrial lactic acid production and define ... -
Investigation of microbial community structure and function underpinning grass and food waste anaerobic digestion
(2016-08-18)Anaerobic digestion (AD) of feedstocks, such as grass and food waste, presents a sustainable and cost efficient technology for the generation of bioenergy and value added products. However, to fully optimize the process, ... -
Linking microbial community structure and function to process performance and reactor configuration during high-rate low-temperature anaerobic treatment of dairy wastewater
(NUI Galway, 2018-09-14)Anaerobic digestion is a sustainable and attractive option for the treatment of wastewaters. It allows the recovery of energy from waste - in the form of biogas - and is more cost-efficient than aerobic biological treatments. ... -
Microbial ecology of methanogenic sludge granulation and its application in the reduction of selenate and selenite
(NUI Galway, 7-05-21)This thesis attempts to address some of the knowledge gaps in the literature around methanogenic granulation. Much existing research focuses on granulation of flocculent biomass up to the point at which satisfactory ... -
Pure culture, co-culture and whole ecosystem investigations of single anaerobes, partnerships and microbial communities in anaerobic digestion
(2017-10-20)Anaerobic digestion (AD) is a multi-stage process whereby biodegradable material is broken down by complex microbial consortia into renewable CH4 in the absence of oxygen during waste and wastewater treatment. Anaerobic ... -
A quantitative and qualitative analysis of microbial community development during low-temperature anaerobic digestion of dairy wastewater
(2012-06-25)The objective of this thesis was to link microbial community structure, population dynamics and microbial activity with performance of two different bioreactor configurations during low-temperature anaerobic digestion of ... -
Sustainable waste management for lipid-rich dairy wastewater by anaerobic digestion
(NUI Galway, 2023-12-18)The efficient anaerobic degradation of long chain fatty acids (LCFA) holds the key to unlocking the energy potential of lipid-rich wastewater in the dairy industry. This study aimed to explore sustainable solutions for the ...
