Sludge treatment

Cholet wastewater treatment plant

As a by-product of wastewater treatment, sludge poses a major economic and environmental challenge. Improved wastewater treatment processes have resulted in significantly higher quantities of sludge to be treated.

However, the constraints represented by the increasing sludge volumes to be treated, can be offset by leveraging the enormous potential of biosolids produced. The potential of a reusable biogas production has to be considered as an input to meet part of the energy needs.

SUEZ water treatment specialists offer a comprehensive range of solutions tailored to each stage of treatment, enabling optimised sludge management while recovering waste to contribute to energy independence and decarbonisation of regions: digestion, thickening, dewatering, drying and incineration.
