Dispersion of inorganic contaminants in surface water in the vicinity of Potchefstroom
Manyatshe, A.; Fosso-Kankeu, E.; Van der Berg, D.; Lemmer, N.; Waanders, F. (Elsevier, 2017)Potchefstroom and the neighbouring cities rely mostly on the Mooi River and Vaal River for their water needs. These rivers flow through the gold mining areas and farms, and are therefore likely to be contaminated with ... -
Flocculant types and operating conditions influencing particles settling rates in feed water used at a coal power plant
Van der Linde, Johannes Cornelius; Fosso-Kankeu, Elvis; Waanders, Frans; Dreyer, Louise; Lemmer, Nico (Desalination Publications, 2019)South Africa is a semi-arid country with an average rainfall less than half of the average rainfall worldwide. From the country limited water resource, 2%–3% of the water is used in energy generation. Thus the water ... -
Metal retention potential of sediment and water quality in the Mooi River, South Africa
Manyatshe, Alusani; Fosso-Kankeu, Elvis; Van der Berg, Divan; Lemmer, Nico; Waanders, Frans (Taylor & Francis, 2017)The potential metal retention by sediments along the Mooi River and connected streams in the vicin - ity of Potchefstroom, South Africa, was evaluated using the four-stage sequential extraction proce - dure. ... -
Metal speciation in the rivers around Potchefstroom based on seasonality
Manyatshe, Alusani; Fosso-Kankeu, Elvis; Van der Berg, Divan; Lemmer, Nico; Waanders, Frans; Tutu, Hlanganani (Water Environment Federation, 2018)About 44 surface water samples were collected in the wet and dry seasons around mining areas near the city of Potchefstroom in South Africa, and physicochemical parameters were analyzed to assess the speciation of pollutants ...
