An investigation into the growth of lolium perenne L. and soil properties following soil amendment with phosphorus-saturated bauxite residue
Cusack, Patricia B.; Healy, Mark G.; Callery, Oisín; Di Carlo, Elisa; Ujaczki, Éva; Courtney, Ronan (Springer, 2022-04-07)Industrial by-products, such as bauxite residue, may be used to treat phosphorus (P)-enriched water and wastewater. Once fully saturated, they may be reused as P fertilisers. This study aimed to investigate the effectiveness ... -
A novel method to rapidly assess the suitability of water treatment residual and crusted concrete for the mitigation of point and nonpoint source nutrient pollution
Callery, Oisín; Healy, Mark G. (Elsevier, 2019-07-02)Freshwater ecosystems worldwide are at risk of becoming degraded as a result of excessive inputs of phosphorus (P) associated with terrestrial activities. This study describes a novel methodology to rapidly assess the ... -
Use of rapid small-scale column tests for simultaneous prediction of phosphorus and nitrogen retention in large-scale filters
Ezzati, Golnaz; Healy, Mark G.; Christianson, Laura E.; Fenton, Owen; Feyereisen, Gary; Thornton, Steven; Callery, Oisín (Elsevier, 2020-07-01)Rapid small-scale column tests (RSSCTs) have been previously used to predict the effluent concentration of a single nutrient in large filters with good accuracy. However, in drainage waters originating from heavy textured ... -
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
Cusack, Patricia B.; Callery, Oisín; Courtney, Ronan; Ujaczki, Éva; O’Donoghue, Lisa M.T.; Healy, Mark G. (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. ...
