Sludge & Biosolids

Managing the increasing sludge volumes generated by municipal and industrial water and wastewater treatment processes is a major environmental challenge for municipalities worldwide.

Your sludge, our resource

At Veolia Water Solutions & Technologies, we see sludge not as a waste but as a potentially valuable resource.

We apply our global technological leadership to help municipal clients extract valuable biosolids and produce agriculturally-beneficial byproducts. By converting sludge into energy, we help offset wastewater treatment plant operation costs.

Our designs minimize sludge generation in the initial phases of water treatment. For sludge that remains after recovery, we minimize weight and volume and remove harmful substances prior to disposal. Our sustainable treatment solutions meet rigorous health and environmental standards.

Key technologies for sludge treatment
