The distribution, type, popularity, size and availability of river-run gravel and crushed stone for use in land drainage systems, and their suitability for mineral soils in Ireland
Byrne, I.; Healy, Mark G.; Fenton, O.; Tuohy, P. (Compuscript for Teagasc (Agriculture and Food Development Authority, Ireland), 2022-06-24)The performance of land drainage systems installed in mineral soils in Ireland is highly variable, and is dependent on, amongst other factors, the quality and suitability of the aggregate used. In Ireland, aggregate for ... -
Effects of wastewater pre-treatment on clogging of an intermittent sand filter
Mohamed, A.Y.A.; Tuohy, P.; Healy, Mark G.; Ó hUallacháin, D.; Fenton, O.; Siggins, A. (Elsevier, 2023-03-11)Intermittent sand filters (ISFs) are widely used in rural areas to treat domestic and dilute agricultural wastewater due to their simplicity, efficacy and relative low cost. However, filter clogging reduces their operational ... -
Evaluation of the fertiliser replacement value of phosphorus-saturated filter media
Arenas-Montaño, V.; Fenton, O.; Moore, B.; Healy, Mark G. (Elsevier, 2021-01-12)The use of filter media to adsorb phosphorus (P) from nutrient-rich waters is an effective, simple and low-cost method to recover and reuse P as an inorganic fertiliser replacement. Although it is assumed that the saturated ... -
Mitigation of ammonia and greenhouse gas emissions from stored cattle slurry using acidifiers and chemical amendments
Kavanagh, I.; Burchill, W.; Healy, Mark G.; Fenton, O.; Krol, D. J.; Lanigan, G. J. (Elsevier, 2019-07-28)Cattle and cow slurry storage is a significant source of agricultural greenhouse gas (GHG) and ammonia (NH3) emissions. While acidification has been demonstrated to significantly reduce these emissions, a knowledge gap ... -
A novel hybrid coagulation-constructed wetland system for the treatment of dairy wastewater
Mohamed, A.Y.A.; Siggins, A.; Healy, Mark G.; Ó hUallacháin, D.; Fenton, O.; Tuohy, P. (Elsevier, 2022-07-29)Constructed wetlands (CWs) are a cost-effective and sustainable treatment technology that may be used on farms to treat dairy wastewater (DWW). However, CWs require a large area for optimal treatment and have poor long-term ... -
A novel hybrid coagulation-intermittent sand filter for the treatment of dairy wastewater
Mohamed, A. Y. A.; Siggins, A.; Healy, Mark G.; Fenton, O.; Ó hUallacháin, D.; Tuohy, P. (Elsevier, 2022-08-06)An intermittent sand filter (ISF) is a simple and cost-effective treatment method that may be adopted on farms to treat dairy wastewater (DWW). However, the use of ISFs has been limited due to the large area required for ... -
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
Murnane, J. G.; Brennan, R. B.; Fenton, O.; Healy, Mark G. (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 ...
