Sludge dewatering improvement

The treatment and disposal of sewage sludge is an expensive and environmentally sensitive problem. It is also a growing problem world-wide since sludge production will continue to increase as new sewage treatment works are built and environmental quality standards become more stringent. Dewatering process efficiency, classically assessed by a parameter “dryness limit”, is strongly affected by conditioned sludge properties and by operating conditions.In this review we discussed the dewatering methods and ways for improving of sludge dewatering.
