Performance of Moringa oleifera seed extract as primary coagulant and as coagulant aid with alum in clarification of turbid coloured water was examined and compared with the performance of alum. M. oleifera seed extract is effective as prime coagulant and as coagulant aid with alum. Compared with alum (residual filtrate turbidity 2 NTU and residual colour 3 TCU), it produces water with slightly higher residual filtrate turbidity (4 and 3 NTU) and residual colour (15 and 13 TCU), but the residual turbidity and residual colour are within the WHO drinking water guideline values for turbidity (5 NTU) and colour (15 TCU).

M. oleifera seed extract is effective as prime coagulant and as coagulant aid with alum. Compared with alum (residual filtrate turbidity 2 NTU and residual colour 3 TCU), it produces water with slightly higher residual filtrate turbidity (4 and 3 NTU) and residual colour (15 and 13 TCU), but the residual turbidity and residual colour are within the WHO drinking water guideline values for turbidity (5 NTU) and colour (15 TCU).
