The water quality of South African rivers is greatly impacted by insufficiently treated
wastewater effluents (de facto reuse). Although de facto reuse serves as an alternative
water supply it poses potential threats to ...
The Vaalkop water treatment works (WTW) abstracts water from the Vaalkop Dam, which is situated in the Crocodile West/Marico Water Management Area of South Africa. The bulk of the inflow into the dam is through a canal fed ...
Acid mine drainage (AMD) is a serious water pollutant that contaminates freshwater sources such as rivers, lakes, ground water and even sediments with heavy metals which include Cr(VI), Cd(II) and Pb(II). In this study a ...
The transport industry is one of the biggest contributors to air pollution, with the major air pollutants being COx, NOx, and SOx. SOx is produced by the combustion of the organic sulphur compound found in fuels, e.g. ...
This dissertation examines the structure and properties of chitosan membranes regarding their applicability in fuel cells. The objective of this work is to synthesize a polymer membrane with improved properties such as ...
The thermochemical conversion of waste tires for chemicals and power production is investigated using process synthesis techniques and experimental analysis. Pyrolysis and gasification technologies were evaluated in terms ...
Industrialization has resulted in the introduction of xenobiotics into the environment.
These chemicals have polluted soil, water, and air, causing significant health concerns.
White rot fungi possess the capability to ...
Municipal wastewater pollution in developing countries is a great concern due to partially treated or untreated wastewater. Inflow and Infiltration (I/I) is a challenge in municipalities that receive stormwater as it impacts ...

Abstract
Tannery industries’ effluent contains a high concentration of Cr (VI) which has the potential to affect the environment and public health. Therefore, this study aimed to investigate the optimization ...
Crude oil is an unrefined petroleum which forms because of dead organisms buried under mud over a long period of time (million years). The mud is then converted to sedimentary rocks, which create intense heat and pressure, ...
The aim of this study was to determine the effects of the feedstock composition, such as biomass, polyethylene and their respective blend ratios, -gasifying agents and operating conditions on the product gas composition, ...
Abstract
Due to their outstanding power density, long cycle life and low cost, supercapacitors have gained much interest. As for supercapacitor electrodes, molybdenum nitrides show promising potential. ...
2, 2, 6, 6-Tetramethylpiperidine-N-oxyl radical (TEMPO) is a stable nitroxyl radical, as well as a highly efficient selective oxidation catalyst. It can efficiently catalyze the selective oxidation of C6 primary hydroxyl ...
Power-to-chemicals processes hold tremendous potential to enable the widespread adoption of
renewable sources of energy and to open many avenues to the green hydrogen economy. These
processes will play a critical role ...
Glycerol is considered as the major waste from biodiesel production since every 1L of biodiesel
produced is accompanied by 0.1 L of glycerol by-product. Utilizing this waste as a biorefinery
feedstock will not only ...
A 2D pseudo-homogeneous fixed bed reactor model was developed using ANSYS Fluent,
based on an actual bench-scale Fischer-Tropsch reactor. The single-tube reactor had a
diameter of 0.05m, which is representative of the ...
Reduced graphene oxide (RGO) supported cobalt based catalysts with or without rhodium promotion,
Rh-Co/RGO (RCG) and Co/RGO (CG), were successfully synthesized and evaluated in both Fischer Tropsch synthesis (FTS) and ...
The industry’s great interest is to intensify the cobalt-based Fischer-Tropsch synthesis (FTS)
process by increasing the per-pass conversion and the production of long chain hydrocarbons. To
achieve this goal, it is ...
Diesel fuel has been found to contain highly concentrated organo-sulphur compounds which have bad impact economically, environmentally, and health-wise. Adsorptive desulphurization (ADS) is one of the promising processes ...
In this study, period four transition metal oxides (Zn, Cr, Mn, Co, Fe, Cu, Ni), acting as
intermediate Lewis acids, were supported on activated carbon (AC) and used in the adsorptive
desulfurization (ADS) of model and ...
