The effectiveness of Moringa Oleifera seed coagulant in reducing the turbidity and modifying the physico-chemical characteristics of water

Moringa oleifera plant is unique due to its coagulation effect on turbid water. However, the extent to which the seed’s powder coagulant changes the physico-chemical characteristics of treated water has not been discussed in previous studies. In addition, there are limited data and information on the optimum concentration of M. oleifera seed powder coagulant and the nature of the sludge that forms after the...

Potential of biochar for clean-up of heavy metal contaminated soil and water

Heavy metals exist in the environment naturally aside those due to anthropogenic impact. These metals are removed from effluents and water using different techniques like adsorption, oxidation/reduction, chemical precipitation, membrane separation, filtration and ion exchange. Biosorption is very effective because it is highly renewed naturally, is cheap, and can remove metals greatly because the pollutant can be...
