Performance and surface clogging in intermittently loaded and slow sand filters containing novel media
(Elsevier ScienceDirect, 2016-05-20)
Slow sand filers are commonly used in water purification processes. However, with the emergence of new contaminants and concern over removing precursors to disinfection by-products, as well as traditional contaminants, ...
Environmental impacts of milk powder and butter manufactured in the Republic of Ireland
(Elsevier, 2016-11-11)
The abolition of the milk quota system that was in place in Europe was abolished in 2015, which instigated an immediate increase in milk production in many European countries. This increase "will aid in addressing the ...
Treatment of landfill leachate in municipal wastewater treatment plants and impacts on effluent ammonium concentrations.
(Elsevier, 2016-12-05)
Landfill leachate is the result of water percolating through waste deposits that have undergone aerobic and anaerobic microbial decomposition. In recent years, increasingly stringent wastewater discharge requirements have ...
The potential for the use of waste products from a variety of sectors in water treatment processes.
(Elsevier ScienceDirect, 2016-07-21)
This review examines the utilisation of waste products from three sectors (industry, agriculture, and construction and demolition) in filters for the removal of contaminants from water. Sand is commonly used in drinking ...
An embodied carbon and embodied energy appraisal of a section of Irish motorway constructed in peatlands
(Elsevier, 2015-01-29)
In addition to the customary drivers of cost and timely project delivery, embodied energy (EE) and embodied carbon (EC) have come to prominence in recent years as major design considerations in all aspects of large-scale ...
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 ...
Using image processing for determination of settled sludge volume
(IWA Publishing, 2018-07-12)
Determination of the sludge volume index is key to describing the settling characteristics of sludge in the aeration process of wastewater treatment plants (WWTPs). The two core components of this calculation are the settled ...
A novel image processing-based system for turbidity measurement in domestic and industrial wastewater
(IWA Publishing, 2018-01-19)
Wastewater treatment facilities are continually challenged to meet both environmental regulations and reduce running costs (particularly energy and staffing costs). Improving the efficiency of operational monitoring at ...
Liquid phase optimisation in a horizontal flow biofilm reactor (HFBR) technology for the removal of methane at low temperatures
(Elsevier, 2014-01-03)
Methane (CH4) is a potent greenhouse gas often emitted in low concentrations from waste sector activities. Biological oxidation techniques have the potential to offer effective methods for the remediation of such emissions. ...
Hydrogen sulfide oxidation in novel Horizontal-Flow Biofilm Reactors dominated by an Acidithiobacillus and a Thiobacillus species
(Taylor & Francis, 2016-03-17)
Hydrogen Sulfide (H2S) is an odourous, highly toxic gas commonly encountered in various commercial and municipal sectors. Three novel, laboratory-scale, Horizontal-Flow Biofilm Reactors (HFBRs) were tested for the removal ...
