Active neutralisation and amelioration of acid mine drainage with fly ash
(University of the Western Cape, 2009)Fly ash and AMD samples were characterised by standard analytical methods for selection of the test materials. Active treatment by means of mixing fly ash with AMD in beakers and a large tank at pre-determined ratios have ... -
Active neutralisation and amelioration of acid mine drainage with fly ash
(University of the Western Cape, 2009)Due to the constraints being placed on water resources and a drive for major industries to recycle waste water, improved and cheaper water treatment technologies are being investigated. During mining, pyrite (FeS2), a ... -
Brine treatment using natural adsorbents
(University of the Western Cape, 2011)The current study investigated application of natural adsorbents in brine treatment. Brines are hypersaline waters generated in power stations and mining industries rich in Mg2+, K+, Ca2+, Na+, SO4 2- , Cl- and traces of ... -
Brine treatment using natural adsorbents
(University of the Western Cape, 2011)Studies involving the use of natural clays such as bentonite, montmorillonite and natural zeolite clinoptilolite in water treatment have been reported. Researchers suggested cost effective processes, such as ion-exchange ... -
Development of capacitive deionisation electrodes: optimization of fabrication methods and composition
(University of the Western Cape, 2020)Membrane Capacitive Deionisation (MCDI) is a technology used to desalinate water where a potential is applied to an electrode made of carbonaceous materials resulting in ion adsorption. Processes and materials for the ... -
Ion exchange resins an functional fibres: a comparative study for the treatment of brine waste water
(University of the Western Cape, 2009)To improve the adsorption capacity of polyacrylonitrile (PAN) fibres, hydrophilic amidoxime fibres were prepared by subsequent conversion of the cyano groups to an amidoxime group by reacting with hydroxylamine at 80°C at ... -
Sorption properties of natural zeolites for the removal of ammonium and chromium ions in aqueous solution
(University of the Western Cape, 2011)There are huge amount of natural clinoptilolite available in South Africa which can be utilised for wastewater treatment of ammonia and chromium if their characteristics are properly known. However, these deposits have not ...
