Abstract
This work evaluates the efficiency of okra powder in removing turbidity, suspended solids and ions of Fe from synthetic raw water through coagulation-flocculation process. The raw water samples with initial turbidity of 100 NTU were prepared using natural red clay (-32+100 mesh particle size). The jar tests were carried out by varying the pH and the dose of okra powder. The initial pH 8.0 of synthetic raw water and 30 mgL-1 okra powder caused 80.92% reduction of Fe ions and 99% turbidity removal after 10 minutes of sedimentation. The efficiency of Fe the removal was evaluated by characterization EDX sludge formed after sedimentation with and without okra powder and the jar tests were carried out using a solution of ferric sulfate as the coagulating agent.
