Thickening and dewatering start the sludge treatment process in order to:
Thickening is essential in order to reduce the volume of the sludge produced by wastewater treatment. It optimises the following conditioning, stabilisation and dewatering phases by reducing the size of facilities and equipment, and the operating costs. Dewatering improves efficiency and optimises operating costs.
Conditioning, which forms the basis of efficient dewatering, aims to artificially increase the size of the particles in order to improve separation and optimise the final dewatering content (*).

SUEZ has developed a number of different sludge thickening and dewatering processes. We recommend a technique according to the characteristics of the sludge and the objectives of the treatment process.
