The presence of toxic metals in surface and natural waters, even at trace levels, poses a great danger to humans and the ecosystem. Although the combination of adsorption and coagulation techniques has the potential to eradicate this problem, the use

Advanced wastewater-treatment techniques such as adsorption are essential in the removal of non- biodegradable toxic wastes from water. In this study, the use of South African coal fly ash, an industrial byproduct, has been investigated as a potentia

This work demonstrated the potential of CNC as a substitute for PEG as an additive in ultrafiltration membrane fabrication. Two sets of modified membranes were fabricated using the phase inversion technique with polyethersulfone (PES) as the base pol

The increase in dye-containing effluents that are discharged into the environment and the need to remediate the water bodies from the adverse effect of these dye pollutants have motivated a lot of research work. In this study, ZnO and TiO2 heterojunc

A new method of predicting fouling is proposed. The method involves the use of membrane autopsy and fractal analysis of the cake layer that was formed on the top of fouled membranes after the filtration experiment. The new method was verified using t
