Abstract
Ferric chloride is an effective coagulant for the removal of suspended solids and appreciable
amount of Chemical Oxygen Demand (COD) in sewage. Treatment of sewage by ferric
chloride produced highly voluminous sludge which was resistant to dewatenng process. Lime
improves dewatering of ferric sludge by reducing specific resistance and increasing the
compressibility characteristic of sludge depending on the dosage of conditioners Flyash was
also concluded as an effective conditioner due to a decrease in the specific resistance of sludge
On the other hand, addition of flyash decreased the compressibility coefficient of sludge
