Feasibility of using kaolin suspension as synthetic sludge sample

In this research, seven coagulants were prepared from Moringa oleifera (MO) seeds and tested on kaolin suspension (5% w/v) as a synthetic sludge (SSL) model. The first form was crude MO seeds powder without any treatment, while the second was defatted MO seeds powder. The third form was prepared by...
