Chitosan and Bentonite as Coagulant in Dissolved Air Flotation Tank

Abstract:

The use of monocoagulants, such as Chitosan, may not be a good solution for highly turbid water purification because of its high cost. The possibility to reduce the amount of the primary coagulant at the same time keeping the removal to be in optimum may be a good strategy to reduce the operation cost. There might be another coagulant aid for example the natural clay of Bentonite to reduce the cost. The initial stage is to determine the Bentonite dosage and mixture ratio to be used with Chitosan. Coagulation of Chitosan-Bentonite had successfully removed the turbidity with the efficiency of 97%. The coagulants performed well when Chitosan-Bentonite ratio is 30:70 at concentration of 1000mg/l
