Study on Fly Ash for Conditioning of Specific Resistance of Sludge Water

Abstract:

Effect of the dosage of flocculants on sludge dewatering is analyzed through the determination of sludge specific resistance to filtration. Sludge dewatering behaviors conditioned on Polymeric aluminum, PAM, fly ash and composite flocculants have been compared. The results show all the conditioning agent have help to sludge dewatering. Fly ash from electric power plant as conditioning agent can greatly reduce the specific resistance of sludge and the dewatering performance can be improved.The optimal dosage of fine powdered coal is 20g/100mL and coarse powdered coal is 30g/100mL.Powdered coal is mixed with sludge to form filter cake which is blended with coal in certain proportion to make into fuel.
