Fluoride removal half-life (t0.5) values were found to increase in the order Ba ≈ stonedust (a 99% pure natural calcite) < Cd < Co < Mn. A barrier width of 0.97 ± 0.02 m was found to be required for the fluoride/calcite (stonedust) only system when using no factor of safety, whilst in the presence of Mn and Co, the width increased to 2.76 ± 0.28 and 19.83 ± 0.37 m respectively. In comparison, the PSO model predicted a required barrier thickness of ∼46.0, 62.6 & 50.3 m respectively for the fluoride/calcite, Mn and Co systems under the same conditions.]]> Wed 04 Dec 2019 12:54:35 AEDT ]]> A pilot scale permeable reactive barrier for the remediation fluoride from groundwater contaminated with aluminium smelter wastes: results and lessons learnt https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:2865 Sat 24 Mar 2018 08:28:46 AEDT ]]> A calcite permeable reactive barrier for the remediation of fluoride from spent potliner (SPL) contaminated groundwater https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:5198 Sat 24 Mar 2018 07:47:47 AEDT ]]>
