Sludge Conditioning

The origins and characteristics of sludges are described in relation to the need to dewater them for ultimate disposal. Various methods for conditioning sludge to facilitate subsequent dewatering are discussed, including physical, thermal and chemical methods. The special features of conditioning by polyelectrolytes are described and an account is given of laboratory techniques for comparing the relative efficiency of conditioners.

Sludge Conditioning

Studies of sewage sludge conditioning by ultrasonic field concentrate on determination of the increase of water removal effect, which depends on kind of sludge and chemical compounds used in the dewatering process. An attempt was made to find new methods of sludge preparation before dewatering. Tests presented here focused on digested and difficult dewatered sludge. The sludge was dewatered on a vacuum filter after conditioning with polyelectrolytes and the ultrasonic field. The microscopic analysis was an additional criterion to evaluate changes in the sludge structure after preparation. The polyelectrolyte dose of 3 mg/g d.m. sonicated within 15 sec. resulted in the 50% decrease of sludge volume. Results presented confirmed our previous experiences, concerning the relation between conglomerates of sludge and the effect of dewatering.
