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
(Elsevier, 2016)
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 ...
Performance analysis of a permanent magnet transverse flux generator with double coil
(IEEE, 2016)
One of the disadvantages of permanent magnet (PM) transverse flux machines is high magnetic flux leakage in the stator and rotor
cores. To improve the magnetic circuit of this class of machines, a generator with double ...
CFD modeling of particle charging and collection in electrostatic precipitators
(Elsevier, 2016)
A CFD model was developed to describe the particle laden gas flow through an ESP, particle charging and collection. The corona discharge was modeled using the open source software OpenFOAM to solve the Poison and charge ...
The effect of particle size on the rate and depth of moisture evaporation from coal stockpiles
(SAIMM, 2016)
Excessive amounts of moisture in product coal can influence the efficiency
of downstream utilization processes due to a decreased calorific value and
handling problems. Stockpiles can be used to decrease the moisture
content ...
Hydrogen production from ammonia decomposition over a commercial Ru/Al2O3 catalyst in a microchannel reactor: experimental validation and CFD simulation
(Elsevier, 2016)
In this work, an integrated experimental and CFD modelling technique was used to evaluate a microchannel reactor producing hydrogen from ammonia decomposition using a commercial Ru/Al2O3 catalyst. The microchannel reactor ...
A review on switched reluctance machines for electric vehicle
(IEEE, 2016)
Nowadays, switched reluctance machines (SRM) are gaining interest in the scientific community due to the advantages they offer. The SRM offers an overall efficiency similar to an induction motor of the same rating, since ...
Preparation and characterization of gum karaya hydrogel nanocomposite flocculant for metal ions removal from mine effluents
(Springer, 2016)
This research paper reports the removal of heavy metal ions from mine effluents using the gum karaya (GK)-grafted poly(acrylamide-co-acrylic acid) incorporated iron oxide magnetic nanoparticles (Fe3O4 MNPs) hydrogel ...
Cloning of the cnr operon into a strain of Bacillaceae bacterium for the development of a suitable biosorbent
(Springer, 2016)
In this study, a potential microbial biosorbent
was engineered to improve its capacity to remediate heavy
metal contaminated water resources. A Bacillaceae bacterium
isolated from a mining area was transformed with ...
Copolymerization of ethyl acrylate onto guar gum for the adsorption of Mg(II) and Ca(II) ions
(Taylor & Francis, 2016)
In the present study, the copolymerization of ethyl acrylate and guar gum was induced by microwave irradiation in the presence of catalytic amount of the initiator potassium persulfate (KPS). The maximum percentage conversion ...
