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’s water treatment specialists provides effective responses to this trend by offering a wide range of processes for every stage of treatment, from thickening digestion , dewatering, drying and incineration.
