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 ...
Pipe reactor gasification studies of a south african bituminous coal blend. Part 1 - Carbon and volatile matter behaviour as function of feed coal particle size reduction
(Elsevier Science Ltd, 2009)
The Sasol-Lurgi fixed-bed dry-bottom (FBDB) MKIV gasifiers are proven to be robust as far as acceptable coal properties are concerned, in particular its ability to accommodate a range of particle size distributions (PSD) ...
