Assessment of anaerobic wastewater treatment failure using terminal restriction fragment length polymorphism analysis
(Wiley-Blackwell, 2005-12-01)Aims: The suitability of genetic fingerprinting to study the microbiological basis of anaerobic bioreactor failure is investigated. Methods and Results: Two laboratory-scale anaerobic expanded granular sludge bed bioreactors, ... -
Bioreactor scalability: laboratory-scale bioreactor design influences performance, ecology, and community physiology in expanded granular sludge bed bioreactors
(Frontiers Media, 2017)Studies investigating the feasibility of new, or improved, biotechnologies, such as wastewater treatment digesters, inevitably start with laboratory-scale trials. However, it is rarely determined whether laboratory-scale ... -
Bioreactor scalability: laboratory-scale bioreactor design influences performance, ecology, and community physiology in expanded granular sludge bed bioreactors
(Frontiers Media SA, 2017-05-01)Studies investigating the feasibility of new, or improved, biotechnologies, such as wastewater treatment digesters, inevitably start with laboratory-scale trials. However, it is rarely determined whether laboratory-scale ... -
Biosafety assessment during anaerobic co-digestion of food waste and pig manure
(NUI Galway, 2022-10-11)Antimicrobial resistance (AMR) spreading has been a public concern as it increases the mortality of infection, and some biowastes (such as pig manure, food waste and municipal waste sludges) have been reported as hotspots ... -
Brewery spent grain cascade process: protein recovery and improved downstream fermentation for simultaneous volatile fatty acid production and recovery
(NUI Galway, 2022-03-23)Volatile fatty acids (VFAs) are short chain carboxylic acids currently produced from fossil fuels. Renewable biomass, including organic wastes, could be used as an alternative source of VFAs. Brewery spent grain (BSG) was ... -
Cold adaptation and replicable microbial community development during long-term low-temperature anaerobic digestion treatment of synthetic sewage
(Oxford University Press, 2018-05-25)The development and activity of a cold-adapting microbial community was monitored during low-temperature anaerobic digestion (LtAD) treatment of wastewater. Two replicate hybrid anaerobic sludge bed-fixed-film reactors ... -
Effect of sawdust addition on composting of separated raw and anaerobically digested pig manure
(Elsevier, 2012)Manures need the addition of carbon-rich bulking agents to conserve N during composting, which increases the cost of the composting process. The recommended proportion of manure / sawdust, based on a carbon (C): nitrogen ... -
Functional responses and adaptation of mesophilic microbial communities to psychrophilic anaerobic digestion
(Oxford University Press, 2015-10-27)Psychrophilic (<20°C) anaerobic digestion (AD) represents an attractive alternative to mesophilic wastewater treatment. In order to investigate the AD microbiome response to temperature change, with particular emphasis on ... -
Functional responses and adaptation of mesophilic microbial communities to psychrophilic anaerobic digestion
(Oxford University Press (OUP), 2015-10-26)Psychrophilic (&lt; 20 degrees C) anaerobic digestion (AD) represents an attractive alternative to mesophilic wastewater treatment. In order to investigate the AD microbiome response to temperature change, with particular ... -
Life cycle assessment of waste water treatment plants in ireland
(International Centre for Sustainable Development of Water, 2016-09-01)The Urban Wastewater Treatment Directive 91/271/EEC introduced a series of measures for the purpose of protecting the environment from the adverse effects of effluent discharge from wastewater treatment plants. There are ... -
Linking microbial community structure and function during the acidified anaerobic digestion of grass
(Frontiers Media, 2018-03-21)Harvesting valuable bioproducts from various renewable feedstocks is necessary for the critical development of a sustainable bioeconomy. Anaerobic digestion is a well-established technology for the conversion of wastewater ... -
