Adsorption of metal ions from fine coal tailings dump waste water using bio-char
Fosso-Kankeu, Elvis; Weideman, Reinhardt; Moyakhe, Dumisane; Campbell, Quentin; Waanders, Frans (EARET, 2018)Coal mining operations produce large amounts of tailings which contains heavy metals. Heavy metals such as cadmium (Cd) can cause environmental problems. The adsorption capacities of biochars produced from spent coffee ... -
Adsorption potential of bentonite and attapulgite clays applied for the desalination of sea water
Nel, Monica; Waanders, Frans B.; Fosso-Kankeu, Elvis (PSRC, 2014)A possible new process for the partial desalination of seawater is to use bentonite clay or attapulgite as an adsorbent. The ion exchange property of these clays, which is a result of the characteristic t-o-t layer ... -
Assessment of the performance of SDS-impregnated brewery waste as suitable adsorbent for the removal of Pb and Cd from water
Fosso-Kankeu, Elvis; Leamy, Meiklejohn; Akinpelu, Enoch; Waanders, Frans (EARET, 2018)— Due to increasing populations and an ever-changing climate, limited water resources are South Africa’s burden. Clean water is important for all living organisms’ health and environmental sustainability. To achieve ... -
Bentonitc clay adsorption affinity for anionic and cationic dyes
Fosso-Kankeu, Elvis; Waanders, Frans; Fraser, Corinne (PSRC, 2014)The incidence of dye pollution in South Africa is quite alarming, requesting effective and affordable techniques to curb further degradation of the limited water resource. Adsorption is an attractive technique due to a ... -

Biosorption of cadmium from water using surfactant impregnated eggshell
Fosso-Kankeu, Elvis; Steenekamp, Gerhard; Akinpelu, Enoch; Waanders, Frans (EARET, 2018)Cadmium (Cd) is regarded as one of the most toxic elements and it causes water pollution when it exceeds the permissible limit. It is currently present in the Mooi River above these permitted levels, and must therefore ... -
Brewery effluent sludge characterization and dewatering to increase potential water recycling capabilities
Fosso-Kankeu, Elvis; Van der Vyver, Christiaan; Moyakhe, Dumisane; Waanders, Frans; De Klerk, Corli (EARET, 2018)In this study various coagulants and flocculants were tested for optimum removal of COD from brewery wastewater. The coagulants used were ferric chloride and an organic coagulant mixture obtained from the brewery company. ... -
Colouring of dolomite, quartzite and dolerite mine dump rocks
Easton, Z.; Waanders, F.B.; Fosso-Kankeu, E. (EARET, 2018)For environmental and aesthetic purposes it has become essential that mine dump rocks either blend into the environment or be used in the production of other products. Lately, there has been a constant need to produce ... -
Effect of fine coal tailing porosity on the mobility and speciation of heavy metals in the leachates
Fosso-Kankeu, Elvis; Olivier, Charl; Moyakhe, Dumisane; Barlow, Brad; Campbell, Quentin; Waanders, Frans (EARET, 2018)The effect of porosity of coal tailings on the mobilization and speciation of heavy metals is important for the implementation of management strategies. In this study, column leaching experiments were carried out to ... -
Effect of temperature and cathode material on power production in an earthenware microbial fuel cell
Fosso-Kankeu, Elvis; Rosslee, Gerhard; Pandey, Sadanand; Waanders, Frans; Marx, Sanette (EARET, 2018)This study investigates the performance of microbial fuel cells (MFCs) fed with municipal sewage water considering parameters such as temperature and cathode materials. Single chamber ceramic MFCs with the cathode exposed ... -
Effect of temperature on the performance of Rheofloc: conductivity removal from RO-reject
Van der Linde, J.C.; Fosso-Kankeu, Elvis; Waanders, F.; Tamane, T.; Gericke, G. (EARET, 2018)South Africa is an arid country with an annual average rainfall less than half of the world’s average rainfall. The industrial sector uses 11% of this limited amount of water. Eskom is one of these users. Within the ... -
Evaluation and prediction of slow pyrolysis products derived from coals of different rank
Pretorius, Gustav N.; Bunt, John R.; Neomagus, Hein; Waanders, Frans B.; Everson, Ray C.; Strydom, Christien A. (Elsevier, 2017)When coal is heated slowly (<10 °C/min), as in the Lurgi Fixed Bed Dry Bottom (FBDB) gasification process, products formed in the pyrolysis region of the gasifier include gas liquor, condensable tar, oil and non-condensable ... -
Experimental study on liquid hydrocarbon formation during pressurized underground coal gasification conditions
Van Dyk, J.C.; Waanders, F.B.; Brand, J.F.; Nguyen, M.; Scheithauer, D. (2018)UCG is a gasification process used to produce synthesis gas from coal in situ (underground in the coal seam) by injecting air or oxygen, with or without steam, into coal seams and extracting the product gas via surface ... -
