Statistical testing of input factors in the carbonation of brine impacted fly ash
(Taylor & Francis, 2012)
A D-optimal design was applied in the study of input factors: temperature, pressure, solid/liquid (S/L) ratio and particle size and their influence on the carbonation of brine impacted fly ash (FA) determined. Both ...
Fate of sulphate removed during the treatment of circumneutral mine water and acid mine drainage with coal fly ash: Modelling and experimental approach
The treatment of acid mine drainage (AMD) and circumneutral mine water (CMW) with South African coal fly ash (FA) provides a low cost and alternative technique for treating mine wastes waters. The sulphate concentration ...
Carbonation of brine impacted fractionated coal fly ash: Implications for CO2 sequestration
Coal combustion by-products such as fly ash (FA), brine and CO2 from coal fired power plants have the potential to impact negatively on the environment. FA and brine can contaminate the soil, surface and ground water through ...
Laboratory study on the mobility of major species in fly ash–brine co-disposal systems: up-flow percolation test
(Springer Verlag, 2013)
Apart from the generation of fly ash, brine (hyper-saline wastewater) is also a waste material generated in South African power stations as a result of water re-use. These waste materials contain major species such as Al, ...
Chemical, mineralogical and morphological changes in weathered coal fly ash: A case study of a brine impacted wet ash dump
The mobility of species in coal fly ash (FA), co-disposed with brine using a wet ash handling system, from a coal fired power generating utility has been investigated. The study was conducted in order to establish if the ...
