Coagulation, flocculation and sedimentation are widely used in water treatment to obtain puredrinking water. Thus, efforts have made to find alternatives to alum. In this study, Starch andDextrin have been chosen as natural coagulants. A set of experiments were carried out, conditionswere varied in (30-500 NTU), and (5-10) for the water turbidity and acidity pH ,respectively.The results showed that Lamella has the ability to increase the efficiency of sedimentation processin flocculation/settling tank due to reduction in surface loading and increasing in a retention time .Ithas also been observed that the efficiency of Lamella was ranged in (50-40%)compared with a Jartest that has efficiency between (60-50%).
