Turbidity removal is primary objective of conventional water treatment. The laboratory study was conducted by jar test process for alum coagulation, flocculation and sand ballasted alum coagulation of surface water with Aloe Vera. The experiments were planned to assess the effectiveness of i) Aloe Vera as a coagulant aid with alum as a coagulant for turbidity removal, ii) micro sand as ballasting agent with Aloe Vera as polymer and alum as coagulant, ii) synthetic polymer used with coagulant and ballasting agent. This study concluded that the alum is effective for turbidity removal for water of varied turbidity levels. Aloe Vera improves turbidity removal by 7 to 15%. The use of micro sand further improves turbidity removal by 10 to 15 % by increasing the weight of precipitate which results in more complete settlement. Aloe Vera is more effective polymer as compared to synthetic polymer when used with alum for turbidity removal.
