Finite difference method to design sustainable infiltration based stormwater management system

Infiltration based stormwater best management practices bring considerable economic, social and ecological benefits. Controlling stormwater quantity and quality are primarily important to prevent urban flooding and minimizing loads of pollutants to the receiving waters. However, there have been growing concerns about how the traditional design approach contributes to the failure of infiltration based BMP’s that...

Evaluation of the current water quality of Lake Hawassa, Ethiopia

The research aimed to evaluate the current wáter quality of Lake Hawassa in order to identify potential pollution sources and suggest appropriate measures. Physico-chemical water quality parameters have been determined by taking duplicate samples from seven sampling sites and the results were compared with WHO and FAO standards. The findings of the study revealed that the concentration of metals such as manganese...

Enhancing the adsorption of Pb(II) and Fe(II) in the reactor by the thermally treated alluvial clay from Far North Cameroon

The objective of this work was to investigate the influence of the thermal treatment of alluvial clay on the ad-sorption capacity of Pb(II) and Fe(II) to reduce clogging during adsorption phenomenon. The chemical,  X- ray  diffraction  (XRD),  Fourier  transform  infrared  spectroscopy  (FTIR),  scanning  electron microscope (SEM) and transmission electron microscopy...
