Abstract: In order to investigate the settling pattern of particles in suspension, series of experiment were conducted on surface water samples from Ureje river in Ado-Ekiti, Ekiti State, Nigeria. Flocculent particles were observed to be present in quiescent settling column from the concentration dept time. Mixing effect was significant, resulting in about 10% removal while the specific mixing times effect selected for evaluation under a constant dosage showed 80% removals. This shows that alum dosage selected for evaluation will cause 80% removal. However, when operating near the optimum of the mixing time or alum dosage, the influence of these parameters is less significant. The results also suggest the presence of a fraction of suspended matter in surface water which is not readily removable by gravity settling.
