Utilization of Natural Coagulant in Turbidity Removal and Oxygen Demand Reduction

Abstract

Access to clean water is the significant need in all nations on the planet in which a great many people and living life forms pass on because of tainted water-related ailments consistently. Various consequences have reported the direct and indirect toxic effects of alum in the form of allergies, tumours and cancers. To exchange alum as coagulants, the mixture of pomegranate peel and banana peel used as coagulants in liquid treatment via coagulationflocculation procedures were examined. pH and coagulants amount were identified for the mixtures of banana peel with pomegranate peel. The investigation conducted found that pomegranate peel can be a good coagulant which can absorb Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). The Dehydration method is found to be more efficient for both pomegranate and banana peels. The most elevated turbidity evacuation rate could be accomplished at arrangement pH of 5-9, 4ml/250ml of bio-flocculant to turbid water measurements. In order to minimize dependency on conventional chemical coagulant, various proportion of banana peels and pomegranate peel (bio-flocculant) to alum was used to achieve the best turbidity removal percentage. For river water and pond water turbidity removal efficiency is 86.32% and 90% using natural coagulant.
