Carbon and nitrogen dynamics and greenhouse gas emissions in constructed wetlands treating wastewaters: a review
(2016-02-17)The removal efficiency of carbon (C) and nitrogen (N) in constructed wetlands (CWs) is very inconsistent and frequently does not reveal whether the removal processes are due to physical attenuation or whether the different ... -
Characterisation and testing of carbon fibre PEEK for linerless composite cryogenic storage tanks
(NUI Galway, 2020-05-07)Cryogenic storage tanks, also known ’cryotanks’, are an important component of space launch vehicles. Cryotanks can form an integral part of the overall structure of the launch vehicle and also represent a significant ... -
Characterization of separated pig manure composted with a variety of bulking agents at low initial C/N ratios
(2011)The aim of this study was to investigate the composting of separated pig manure solids with or without a variety of bulking agents at a low initial C/N ratio (12.5-23.3). Compost stability was investigated using an oxygen ... -
Combined zeolite and chemical amendments mixed with agricultural wastes to reduce surface and leaching losses of nutrients and greenhouse gas emissions, and biofilter treatment of dairy soiled water
(2017-05-08)Agricultural activity is a major source of nutrient emissions to surface and ground waters and a significant contributor to greenhouse gas emissions. Despite legislation to improve terrestrial water quality, prescribed ... -
The Impact of Biochar Addition on Nutrient Leaching and Soil Properties from Tillage Soil Amended with Pig Manure
(Springer, 2014-02)The application of pig manure to a tillage soil can result in pollution of surface and groundwater bodies. Countries in the European Union are required to comply with the Water Framework Directive, which states that all ... -
The use of laboratory sand, soil and crushed-glass filter columns for polishing domestic-strength synthetic wastewater that has undergone secondary treatment
(Taylor & Francis, 2010)The aim of this study was to examine the performance of intermittently loaded, 150 mm-diameter stratified filter columns of 2 depths (0.65 and 0.375 m) comprising different media - sand, crushed glass and soil - in polishing ... -
Use of zeolite with alum and polyaluminum chloride amendments to mitigate runoff losses of phosphorus, nitrogen, and suspended solids from agricultural wastes applied to grassed soils
(Crop Science Society of America, 2015-09-16)Carbon (C) losses from agricultural soils to surface waters can migrate through water treatment plants and result in the formation of disinfection by-products (DBP), which are potentially harmful to human health. This study ...
