Destabilization dynamics of clay and acid-free polymers of ferric and magnesium salts in AMD without pH adjustment
(IWA Publishing, 2016)
The physicochemical treatment was employed to treat acid mine drainage (AMD) in the removal of turbid materials using clay only (exp A) and a combination of clay, FeCl3 and Mg(OH)2 (exp B) to form a polymer. A 5 g sample ...
Tailored surface energy of stainless steel plate coupons to reduce the adhesion of aluminium silicate deposit
Fouling in heat exchangers not only reduces heat transfer performance significantly, but also causes considerable pressure drop, resulting in higher pumping requirements. It would be much more desirable if surfaces which ...
Thermodynamic properties and adsorption behaviour of hydrogel nanocomposites for cadmium removal from mine effluents
This research paper reports on the utilization of the hydrogel of gelatine (GL) and its hybrid nanocomposite with clinoptilolite for the adsorption of Cd2+ ions from an aqueous solution and multi-metal ions from mine ...
A survey of the state of condition-based maintenance (CBM) in the nuclear power industry
Condition-based maintenance (CBM) involves undertaking maintenance activities based on the health of the system. CBM has found useful applications in many industries. This paper presents a survey on the state of condition-based ...
Adapting mobile medical information search to low-resourced areas
Providing good medical care in low-resourced areas is a challenge faced by many low and middle income countries. Continuously improving mobile communication infrastructure in these areas is however providing the opportunity ...
Thermal and efficiency analysis of a single phase induction motor with Peltier devices
(Multi-Science Publishing, 2012)
We present the results obtained from the thermal and efficiency analysis of a single phase induction motor with Peltier devices. A single phase induction motor is completely simulated in SolidWorks® and Matlab® Simulink®. ...
Speech data collection in an under-resourced language within a multilingual context
(International Research Institute MICA, 2014)
In this paper, we present an end-to-end solution to the development of an automatic speech recognition (ASR) system in typical under-resourced languages, where the target language is likely to be influenced by one more ...
Update temperature control for a Claus unit with neural networks
(Gulf Publishing Company, 2013)
The Natref Oil Refinery in Sasolburg, South Africa, experienced refractory problems in the combustion chamber of the Sulphur Recovery Unit (SRU) since start-up (Figure 1). Even though the SRU was at all times operated ...
X-ray diffraction parameters and reaction rate modeling for gasification and combustion of chars derived from inertinite-rich coals
An investigation was undertaken to determine the effect of carbon structural properties on the reactivity of chars derived from inertinite-rich coal. The structures of chars were characterized by X-ray diffraction and ...
