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 ... -
Predicting the long-term performance of low-cost phosphorus-sorbing materials using small-scale adsorption column experiments
Callery, Oisín (2017-07-31)Anthropogenic phosphorus (P) and nitrogen (N) inputs to aquatic environments have rapidly increased in magnitude since the middle of the twentieth century, and nutrient pollution has become the primary threat to global ... -
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. ...
