Environmental assessment of freshwater aquaculture in Ireland
(NUI Galway, 2020-12-11)Aquaculture is the fastest growing food production activity in the world and has been for the last several decades. With over 60% of wild fish stocks at or below their maximum sustainable yield, it is expected that to ... -
Evaluation Of Biogas Production From Anaerobic Digestion Of Pig Manure And Grass Silage
(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 ... -
Evaluation of modified flow-through pulsed UV technology for bacterial inactivation with comparison to a standard continuous-flow low pressure UV system
(NUI Galway, 2019-01-24)Approximately 8,000 million litres of milk were processed by the Irish dairy industry in 2017. The most recent data indicates that industry water consumption rates average 2.5m3/m3 of milk processed and 14.9 m3/tonne ... -
Experimental and finite element investigations of the serviceability behaviour of CLT floors
(NUI Galway, 2020-02-06)Global environmental concerns with regard to sustaining our growing population is prompting the building community worldwide to increase urban density, while using optimised and sustainable resources. The traditional ... -
FastDetect: Design of a performance monitoring methodology based on data analytics for large-scale water distribution systems in industrial settings
(NUI Galway, 2022-03-25)Large non-residential buildings can contain complex and often inefficient water distribution systems. As requirements for water increase due to water scarcity and industrialization, it has become increasingly important to ... -
Fatigue lifetime assessment of glass fibrereinforced composite wind and tidal turbine blades
(NUI Galway, 2023-11-24)Wind and tidal turbines have garnered significant interest due to their capability to exploit wind and water currents as sources of renewable energy. These turbines are constituted of various components, amongst which ... -
The impact of chemically amended pig slurry on surface runoff, leachate and greenhouse gasses.
(2013-08-27)In Ireland, the pig industry is concentrated in a small number of counties. Pig farms typically have a high stocking rate. Therefore, the disposal of slurry in a cost-effective and environmentally-responsible way is a ... -
Improvement of sludge dewaterability using filamentous fungi and energy recovery from thermal treatment of sludge
(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. ... -
The influence of silvicultural practices on mechanical properties of softwood timber
(NUI Galway, 2019-06)The increase in the use of structural timber in construction over recent years has been one of the main drivers behind the renewed interest in optimizing forest management for timber quality. Past research and forest ... -
Inhibition of metabolic intermediates and enhancement of methane production in dry anaerobic digestion
(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 ... -
A Mathematical and Numerical Examination of Wave-Current Interaction and Wave-Driven Hydrodynamics
(2010-04-28)A new derivation of an elliptic extended mild-slope wave equation, including the effects of energy dissipation and current, has been accomplished. A Galerkin-Eigenfunction method was used for this derivation and the final ... -
Mechanisms of iron sulfide-based autotrophic denitrification for removal of nutrients and emerging contaminants from carbon-deficient wastewater
(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 ... -
Mineral fertiliser equivalence value of dairy processing waste and derived strubias products
(NUI Galway, 2023-03-09)Globally, agriculture urgently needs alternative sources of phosphorus (P). Presently, global agriculture is over-reliant on inorganic mineral P fertilisers sourced from finite mining sources. This is especially relevant ... -
Model predictive control for efficient operation of district cooling generation
(NUI Galway, 2023-04-21)The market for District Cooling Systems (DCS) is increasing in Europe as well as other parts of the world due to climate change and higher demand for thermal comfort in the buildings. The DCS have come into attention ... -
Modelling a batch biofilm passive aeration process using an activated sludge process and a biofilm process
(2015-05-29)Recently, mathematical modelling of wastewater treatment plants has become a widely used tool for planning, designing, optimising and evaluating wastewater treatment plants (WWTPs). While wastewater models can provide ... -
Modelling the response of influent volumes of wastewater treatment plants under current and future conditions for effective wastewater management in combined sewerage systems
(NUI Galway, 2023-09-28)Wastewater treatment plants (WWTPs) are critical infrastructure globally and are essential to protect public health and the environment. With factors such as population growth, urbanisation, increase in water consumption ... -
Nitrogen removal using partial nitritation-anammox process
(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 ... -
