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 ...
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 ...
Predicting the propagation of concentration and saturation fronts in fixed-bed filters
(IWA Publishing, 2017-07-05)
The phenomenon of adsorption is widely exploited across a range of industries to remove contaminants from gases and liquids. Much recent research has focused on identifying low-cost adsorbents which have the potential to ...
Use of amendments in a peat soil to reduce phosphorus losses from forestry operations
(Elsevier, 2015-10-18)
Forestry harvesting on peats is known to result in significant losses of soil phosphorus (P) to adjacent waters, and the issue is becoming an increasingly serious concern as peatland forest stocks mature and reach harvestable ...
Nutrient dynamics in a peatland forest riparian buffer zone and implications for the establishment of planted saplings
(2012)
Forestry on peatland throughout the world is now focused on minimising destructive effects to the surrounding environment, especially during harvesting. These effects may be mitigated through the use of well-developed ...
Chemical amendment of pig slurry: control of runoff related risks due to episodic rainfall events up to 48 hours after application.
(2013)
Losses of phosphorus (P) from soil and slurry during episodic rainfall events can contribute to eutrophication of surface water. However, chemical amendments have the potential to decrease P and suspended solids (SS) losses ...
Nutrient dynamics in a peatland forest riparian buffer zone and implications for the establishment of planted saplings.
(2012)
Forestry on peatland throughout the world is now focused on minimising destructive effects to the surrounding environment, especially during harvesting. These effects may be mitigated through the use of well-developed ...
Future phosphorus: advancing new '2D' allotropes and growing a sustainable bio economy
(Crop Science Society of America with American Society of Agronomy and Soil Science Society of America, 2019-07-11)
With more than 40 countries currently proposing to boost their national bioeconomies, there is no better time for a clarion call for a new bioeconomy, which, at its core, tackles the current disparities and inequalities ...
Split phosphorus fertiliser applications as a strategy to reduce incidental phosphorus losses in surface runoff
(Elsevier, 2019-04-24)
Organic soils have low sorption capacities for phosphorus (P), and may pose a risk of P loss to water if P applications to these soils coincide with runoff events. Little is known about the magnitude of exports of P in ...
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 ...
