Biosorption of cadmium from water using surfactant impregnated eggshell
(EARET, 2018)
Cadmium (Cd) is regarded as one of the most toxic
elements and it causes water pollution when it exceeds the
permissible limit. It is currently present in the Mooi River above
these permitted levels, and must therefore ...
Assessment of the performance of SDS-impregnated brewery waste as suitable adsorbent for the removal of Pb and Cd from water
(EARET, 2018)
— Due to increasing populations and an ever-changing
climate, limited water resources are South Africa’s burden. Clean
water is important for all living organisms’ health and
environmental sustainability. To achieve ...
Effect of temperature and cathode material on power production in an earthenware microbial fuel cell
(EARET, 2018)
This study investigates the performance of microbial
fuel cells (MFCs) fed with municipal sewage water considering
parameters such as temperature and cathode materials. Single
chamber ceramic MFCs with the cathode exposed ...
Hydrothermal synthesis, characterization and adsorption testing of MoS2-Zeolite for the removal of lead in an aqueous solution
(EARET, 2018)
The shortage of water can be worsened by the
pollution of limited water resources by industrial activities such as
mining which contribute to significant level of toxic heavy metals
in the environments. Heavy metals ...
Sol-gel preparations of ZnO/SnO2 composite photocatalysts applied for the degradation of PAH’s under visible light
(EARET, 2018)
Wastewater treatment challenges faced by
conventional methods have necessitated the need for
alternative/complementary methods that are environmentally
benign and efficient especially toward recalcitrant organic
pollutants. ...
Removal of COD from biodiesel wastewater using a hydrophobic polymer
(EARET, 2018)
Biodiesel production is increasing internationally as
an alternative fuel. This is due to the rapid depletion of
non-renewable energy sources. Pure biodiesel product can be
obtained by washing the product with hot water. ...
Mineralogical observation made during the kinetic dissolution study of chalcopyrite mineral in sulphate media under free pH at room temperature
(EARET, 2018)
An attempt to determine the various
phenomena at play and leaching mechanism of chalcopyrite
dissolution, was conducted on a chalcopyrite concentrate.
The study was performed at atmospheric conditions (room
temperature) ...
Brewery effluent sludge characterization and dewatering to increase potential water recycling capabilities
(EARET, 2018)
In this study various coagulants and flocculants were
tested for optimum removal of COD from brewery wastewater.
The coagulants used were ferric chloride and an organic coagulant
mixture obtained from the brewery company. ...
Effect of fine coal tailing porosity on the mobility and speciation of heavy metals in the leachates
(EARET, 2018)
The effect of porosity of coal tailings on the
mobilization and speciation of heavy metals is important for the
implementation of management strategies. In this study, column
leaching experiments were carried out to ...
Reduction of salinity of water using acrylamide-based polyampholyte
(EARET, 2018)
Polyampholytes are charged macromolecules, which carry both acidic and basic groups. These groups dissociate, leaving ions on chains and counter ions in solution, under appropriate conditions, ...
