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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Removal of organic carbon, nitrogen and phosphorus from wastewater using a novel biofilm reactor
O'Reilly, Edmond (2011-08-08)During this research study, a pumped flow biofilm reactor (PFBR) technology developed at NUI Galway for decentralised wastewater treatment was examined at laboratory scale and field scale. The PFBR technology comprised two ... -
Treatment of Piggery Wastewater Using Woodchip Biofilters
Carney, Kathryn N. (2012-09-21)Pig production is the third most important sector in Irish agriculture and it is a highly intensive industry with over 70% of commercial sows in herds of 500 or greater in 2011. It is estimated that 3.1 million tonnes ... -
Utilization of nanostructured iron sulfides to remove metals and nutrients from wastewater
Yang, Yan (2017-02-15)Wastewater containing metals and nutrients is a global environmental issue, threatening human life and natural ecosystems. Iron sulfide minerals are abundant on Earth and are commonly discarded as mine wastes, causing acid ...
