  • Biological U(VI) reduction in a fixed-bed bioreactor using radiotoxic tolerant mixed-culture of bacteria 
    Mtimunye, Phalazane Johanna; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2018)
    Nuclear energy has been proposed as an alternative energy source in the bid to reduce carbon emissions that results from fossil fuel. Hexavalent uranium [U(VI)] is the most abandoned radioactive waste discharged from nuclear ...
  • Heat-constrained modelling of calcium sulphate reduction 
    Jordan, Luke; Van Vuuren, David (Southern African Institute of Mining and Metallurgy, 2022-10)
    A two-dimensional finite difference model has been developed to describe the reduction of kilogram quantities of dehydrated phosphogypsum. The model’s scope has been limited to focus on the heat transfer and reactions ...
  • Phenol degrading and chromium (VI) reducing biofilm system : effect of shock-loading 
    Matsena, Mpumelelo Thomas; Igboamalu, Tony Ebuka; Chirwa, Evans M.N. (The Italian Association of Chemical Engineering, 2018)
    Hexavalent chromium [Cr(VI)] which are discharged together with organic pollutants in effluent streams from industry pose a health hazard to humans. The present study observed the reduction of Cr(VI) in presence of phenol ...
