The use of digital resources in civil engineering education: student learning and achieving accreditation criteria
(Cambridge Scholars Publishing, 2012)
The use of digital resources in higher education has risen significantly over the last ten years and will continue to do so for the foreseeable future. The challenge for educational instructors is in determining how to ...
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 ...
Enhancement of bauxite residue as a low-cost absorbent for phosphorus in aqueous solution, using seawater and gypsum treatments.
(Elsevier, 2018-01-20)
Bauxite residue (red mud), the by-product produced in the alumina industry, is being produced at an estimated global rate of approximately 150Mt per annum. Due to its highly alkaline nature, many refineries use neutralisation ...
Performance of novel media in stratified filters to remove organic carbon from lake water
(IWA Publishing, 2016-08-15)
Disinfection by-products (DBPs) are an ever-increasing occurrence in water networks, particularly those which abstract water from peatland areas. Although much research has been carried out to discover novel methods to ...
Quantitative risk assessment of antimicrobials in biosolids applied on agricultural land and potential translocation into food
(Elsevier, 2017-12-30)
The use of biosolids as a fertiliser may be an indirect route for contaminants into the food chain. One of the main concerns regarding the spreading of biosolids on agricultural land is the potential uptake of contaminants ...
Metal concentrations in lime stabilised, thermally dried and anaerobically digested sewage sludges.
(Elsevier ScienceDirect, 2015-11-25)
Cognisant of the negative debate and public sentiment about the land application of treated sewage sludges ( biosolids ), it is important to characterise such wastes beyond current regulated parameters. Concerns may be ...
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 ...
Seasonal patterns of metals and nutrients in Phragmites australis (Cav.) Trin. ex Steudel in a constructed wetland in the west of Ireland.
(Elsevier, 2017-07-23)
An understanding of the seasonal variation in the standing stock of metals and nutrients in emergent vegetation of constructed wetlands (CWs), as well as the amounts present in aboveground (AG) and belowground (BG) biomass, ...
Review: the environmental status and implications of the nitrate time lag in Europe and North America.
(Springer Verlag, 2017-08-14)
The efficacy of water quality policies aiming to reduce or prevent nitrate contamination of waterbodies may be constrained by the inherent delay or Btime lag^ of water and solute transport through unsaturated (soil) and ...
Habit suitability assessment of constructed wetlands for the Smooth Newt (Lissotriton vulgaris [Linnaeus, 1758]): a comparison with natural wetlands
(Elsevier, 2017-06-22)
Given the current decline of natural wetlands worldwide and the consequent negative impacts on amphibians, wetlands constructed for the treatment of wastewaters have the potential to play a role in the protection of these ...
