The use of rapid, small-scale column tests to determine the efficiency of bauxite residue as a low-cost adsorbent in the removal of dissolved reactive phosphorus from agricultural waters
(Elsevier, 2019-04-19)
Bauxite residue, the by-product produced in the alumina industry, is a potential low-cost adsorbent in the removal of phosphorus (P) from aqueous solution, due to its high composition of residual iron oxides such as hematite. ...
Developing and validating a decision support tool for media selection to mitigate drainage waters
(Elsevier, 2019-07-26)
The nitrate nitrogen (NO3-N) and ammonium (NH4-N) and/or dissolved reactive phosphorus (DRP) load in drainage water from farms can be managed by reactive or biological media filters. The nutrient content of the drainage ...
Holistic evaluation of field-scale denitrifying bioreactors as a basis to improve environmental quality.
(Association of Crop, Soil and Environmental Societies (ACSES), 2015-10-02)
Denitrifying bioreactors effectively convert nitrate-nitrogen (NO3-N) to di-nitrogen and thereby protect water quality in agricultural landscapes. In the present study, the performance of a pilot-scale bioreactor (50 m ...
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 ...
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 ...
