Appraisal and ranking of poly-aluminium chloride, ferric chloride and alum for the treatment of dairy soiled water
(Elsevier, 2020-04-29)
Land spreading of dairy soiled water (DSW) may result in pollution of ground and surface waters. Treatment of DSW through sludge-supernatant separation using chemical coagulants is a potential option to reduce the negative ...
Management and rehabilitation of peatlands: the roles of water chemistry, hydrology, policy, and emerging monitoring methods to ensure informed decision making
(Elsevier, 2022-04-03)
As the world's most abundant source of terrestrial carbon, peatlands provide numerous ecosystem services, including habitat biodiversity and freshwater quality. Land and water management practices in relation to peatlands, ...
Investigating the suitability of synthetic envelopes as an alternative or complement to stone aggregate in clay-textured soils in Ireland
(Elsevier, 2022-12-21)
In Ireland, agricultural landscapes dominated by high rainfall and poorly drained soils have high densities of in-field pipe drains surrounded by stone aggregate envelopes. Unlike other countries, there is limited availability ...
A framework for determining unsaturated zone time lags at catchment scale
(Elsevier Masson, 2016-12-10)
The responses of waterbodies to agricultural programmes of measures are frequently delayed by hydrological time lags through the unsaturated zone and groundwater. Time lag may therefore, impede the achievement of remediation ...
Evaluating long-term performance of low-cost adsorbents using small-scale adsorption column experiments
(Elsevier, 2016-05-31)
This study investigated a novel method of predicting the long-term phosphorus removal performance of large-scale adsorption filters, using data derived from short-term, small-scale column experiments. The filter media ...
Effects of substrate stress and light intensity on enhanced biological phosphorus removal in a photo-activated sludge system
(Elsevier, 2020-11-06)
Photo-activated sludge (PAS) systems are an emerging wastewater treatment technology where microalgae provide oxygen to bacteria without the need for external aeration. There is limited knowledge on the optimal conditions ...
Dairy processing sludge and co-products: a review of present and future re-use pathways in agriculture
(Elsevier, 2021-06-22)
The dairy industry is one of the largest global producers of wastewater and generates huge volumes of dairy processing sludge (DPS). There are two main types of DPS, lime-treated dissolved air floatation sludge and ...
Pyrolysed waste materials show potential for remediation of trichloroethylene-contaminated water.
(Elsevier, 2019-12-17)
Trichloroethylene (TCE) is an Environmental Protection Agency priority pollutant associated with cancer in humans. With numerous industrial applications and regular landfill disposal, TCE is a common landfill leachate ...
Impact of P inputs on source-sink P dynamics of sediment along an agricultural ditch network
(Elsevier, 2019-12-19)
Phosphorus (P) loss from intensive dairy farms is a pressure on water quality in agricultural catchments. At farm scale, P sources can enter in-field drains and open ditches, resulting in transfer along ditch networks and ...
An assessment of potential pesticide transmission, considering the combined impact of soil texture and pesticide properties: A meta-analysis
(Wiley, 2022-02-22)
Pesticides are widely employed as a cost-effective means of reducing the impacts of undesirable plants and animals. The aim of this paper is to develop a risk ranking of transmission of key pesticides through soil to ...
