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. ... -
Co-digestion of sweet sorghum bagasse with scientific and crude glycerols for electricity generation
Fosso-Kankeu, Elvis; Marx, Sanette; Ribberink, Jandri A.; Van den Bergh, Jacobus P.J. (PSRC, 2014)With the global fossil fuel supplies dwindling and the alarming increase of carbon dioxide in the atmosphere, the need for alternative, clean energies, from carbon neutral sources is pressing. This impetus advanced research ... -
Column leaching of fine coal tailings: impact on environment and thickener operation
Moyakhe, Dumisane; Fosso-Kankeu, Elvis; Campbell, Quentin (EARET, 2018)The coal mining sector is synonymous with generating large quantities of waste. A comprehensive fraction of the waste is classified as fines (-500 µm) and ultrafine (-100 µm) particles, which accounts eleven per cent ... -
Comparative adaptation of B. subtilis and P. aeruginosa in diesel supplemented medium and impact on biodegradation potential
Fosso-Kankeu, Elvis; Marx, Sanette; Brink, Antonie (PSRC, 2014)The degree of diesel blending is likely to influence its toxicity as well as the susceptibility and speed of biodegradation. It is therefore imperative to identify strains that can degrade diesel blend in record time, such ... -
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.
