Increasingly sludge is being viewed and treated as a source of valuable by-products and agriculturally beneficial ingredients, such as phosphorus extracted from struvite. For many sites, however, the real pay-off comes in the capacity to recover energy. Proven technologies such as anaerobic digestion, thermal hydrolysis, co-digestion or thermal drying are converting sludge/bio-solids into a valuable energy source.
Sludge as a Resource
Managing the increasing sludge volumes generated by municipal and industrial water and wastewater treatment processes is a major environmental challenge worldwide.
At Veolia Water Technologies, we see sludge not as a waste but as a potentially valuable resource.
Technologies we apply to treat and leverage value from sludge includes:
We apply our global technological leadership to help clients extract valuable bio-solids and produce beneficial by-products. By converting sludge into energy, we help offset wastewater treatment plant operation costs.
Our designs minimise sludge generation in the initial phases of water treatment. For sludge that remains after recovery, we minimise weight and volume and remove harmful substances prior to disposal. Our sustainable treatment solutions meet rigorous health and environmental standards.
