Application of electrodialysis for nutrient recovery from Anaerobic digestate
Meng, Jizhong (NUI Galway, 2023-03-30)Electrodialysis (ED) is an electro-driven membrane-based technology, which can separate ions from solutions with high efficiency. Recently, ED has been studied to recover nutrients, i.e., ammonium (NH4 +) and phosphate ... -
Application of electrodialysis into nutrient recovery and antibiotics removal for pig manure management
Shi, Lin (NUI Galway, 2019-07-25)Animal manure should be regarded as a resource rather than a waste as it contains abundant nutrients (nitrogen and phosphorus) available for plants. Land spreading of animal manure is a common practice while it has to be ... -
Biosafety assessment during anaerobic co-digestion of food waste and pig manure
Wang, Shun (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 ... -
Comparison of intermittently aerated sequencing batch reactors (IASBRs) and conventional sequencing batch reactors (cSBRs) in wastewater treatment
Henry, Liam Garry (2014-01-08)Increasingly stringent discharge standards, increased water usage, variations in wastewater characteristics and climate change have resulted in increased difficulty in achieving cost effective wastewater treatment. The ... -
Energy recovery and pathogen inactivation with dry co-digestion of food waste and pig manure
Jiang, Yan (NUI Galway, 2019-03-14)Anaerobic digestion is one of the best available technologies for food waste (FW) and pig manure (PM) management by producing methane-rich biogas. However, mono digestion of FW or PM is easily inhibited by high volatile ... -
Environmental impacts of milk powder and butter manufactured in the Republic of Ireland
Finnegan, William; Goggins, Jamie; Clifford, Eoghan; Zhan, Xinmin (Elsevier, 2016-11-11)The abolition of the milk quota system that was in place in Europe was abolished in 2015, which instigated an immediate increase in milk production in many European countries. This increase "will aid in addressing the ... -
Evaluation Of Biogas Production From Anaerobic Digestion Of Pig Manure And Grass Silage
Xie, Sihuang (2012-10-19)The research project evaluated biogas production from anaerobic co-digestion of pig manure (PM) and grass silage (GS) in laboratory- and pilot- scale studies. In addition, improvement of the biogas yield from GS via ... -
Improvement of sludge dewaterability using filamentous fungi and energy recovery from thermal treatment of sludge
Yang, Qingfeng (NUI Galway, 2022-06-20)Nowadays, the increasing production of municipal sludge requires effective and suitable disposal methods. The commonly used methods include thickening, dewatering, anaerobic digestion, composting, and thermal treatment. ... -
Inhibition of metabolic intermediates and enhancement of methane production in dry anaerobic digestion
Wang, Zhongzhong (NUI Galway, 2022-07-15)Dry anaerobic digestion (AD) is advantageous over wet AD in treating high-solid organic wastes (e.g., livestock and food wastes). However, it often suffers from low methane production and metabolic intermediates inhibition ... -
Livestockwaste 2016- international conference on recent advances in pollution control and resource recovery for the livestock sector

Mechanisms of iron sulfide-based autotrophic denitrification for removal of nutrients and emerging contaminants from carbon-deficient wastewater
Bai, Yang (NUI Galway, 2023-09-19)Autotrophic denitrification is a biological nitrogen removal process in which nitrate (NO3 - ) is reduced to nitrogen gas (N2) by chemoautotrophic denitrifying bacteria in the presence of inorganic electron donors ... -
Microbial Lipid production from potato processing waste water and simultaneous nutrient removal using oleaginous fungi
Muniraj, Iniya Kumar (2012-10-09)Microbial lipids can be used as a feedstock for biodiesel production, and use of biowastes as the substrate for microbial lipid production can reduce its production cost. The aims of this research include: (i) isolation ... -
Microbiological characterisation and impact of suspended solids on pathogen removal from wastewaters in dairy processing factories
Fitzhenry, Kelly; Rowan, Neil; Finnegan, William; Zhan, Xinmin; Clifford, Eoghan (Cambridge University Press, 2018-08-29)In this Research Communication we investigate the microbiological profile of 12 dairy wastewater streams from three contrasting Irish dairy processing factories to determine whether faecal indicators/pathogens were present ... -
Nitrogen removal using partial nitritation-anammox process
Qiu, Songkai (NUI Galway, 2019-07-26)The partial nitritation-anammox (PN-A) process is a promising biological nitrogen-removal process. Compared with the conventional autotrophic nitrification-heterotrophic denitrification process, it requires no organic ... -
Operational and economic perspectives of pig manure and food waste anaerobic co-digestion
Dennehy, Conor (2017-05-21)On-farm anaerobic co-digestion of pig manure (PM) and food waste (FW) is practiced at commercial scale across the world. However, there is a paucity of information regarding how to optimise such co-digestion systems in ... -
Performance of denitrifying phosphate removal via nitrite from slaughterhouse wastewater treatment at low temperature
Pan, Min; Huang, Xiaoming; Wu, Guangxue; Hu, Yuansheng; Yang, Yan; Zhan, Xinmin (MDPI AG, 2017-10-31)This study aims to investigate the effects of the organic loading rate (OLR) and the aeration rate on denitrifying phosphate removal (DPR) from slaughterhouse wastewater treated at a temperature of 11 degrees C. Three ... -
Phosphorus recovery through adsorption using iron modified cellulose
Silva Simplicio, Walquiria (NUI Galway, 2020-04-24)Phosphorus is an important non – renewable resource, widely used as fertiliser to maintain high crop yields. As the global phosphate reserves will be exhausted in 40 – 150 years, there is a need to explore alternatives to ... -
