pH value increased as the quantity of carbide added increased with time. This could be due to the assumed calcium hydroxide produced from the reaction of sewage with calcium carbide since calcium hydroxide is a base. Calcium carbide can therefore be used in the reduction of BOD, COD and coliform bacteria in sewage.
