A seeded ambient temperature ferrit process for the treatment of AMD waters: Magnetite formation in the presence and absence of calcium ions under steady state operation

Author: Morgan, B E ; Lahav, O ; Hearne, G ; Loewenthal, R E Date: 2003 An ambient temperature ferrite process has been developed for the removal of iron and non-ferrous metals from AMD waters. The process involves the controlled formation of magnetite (Fe3 O4 ) that has the capacity to substitute divalent and ... Read more
Computational Inverse Analysis of Prestressed Concrete Structures

Author: Dezire, Mikael Etienne Date: 2015 Prestressed concrete has gain popularity in the civil engineering industry and found its use in structures such as bridges, nuclear power vessels, monumental towers etc. Conventional approach in designing and analyzing prestressed concrete ... Read more
Fullscale implementation of external nitrification biological nutrient removal in the Daspoort Water Care Works

Author: Muller, A W ; Wentzel, M C ; Saayman, G B ; Van de Merwe, S A ; Esterhuyse, C M ; Snyman, J S ; Ekama, G A Date: 2004 In the external nitrification (EN) biological nutrient removal (BNR) activated sludge (AS) system, the nitrification process is removed from the main BNRAS system to a fixed media system external to the AS system (Hu et al., 2003). The ENBNRAS ... Read more
Modelling organic material in activated sludge systems

Author: Ekama, G A ; Wentzel, M C Date: 2004 A simple predictive model for the activated sludge reactor inorganic suspended solids (ISS) concentration is presented. It is based on the accumulation of influent ISS in the reactor and an ordinary heterotrophic organism (OHO) ISS content ... Read more
Proper Orthogonal Decomposition – Based Material Parameter Identification

Author: Solomons, Simeon Date: 2015 With regard to efficiency in the design and manufacturing of structural elements it was found that understanding constitutive material laws is essential to civil engineers. When modelling engineering materials engineers face the task of making ... Read more
The measurement and reduction of urban litter entering stormwater drainage systems: Paper 2 - Strategies for reducing the litter in stormwater drainage systems

Author: Marais, Mark ; Armitage, Neil Date: 2004 A previous South African study looked at the removal of litter from the drainage systems once it was already there. Yet the litter problem cannot be addressed in an effective and sustainable manner without an effective integrated catchmentwide ... Read more
