Veolia helps communities and industry ensure energy and water reliability, meet regulatory requirements and safeguard public health, all while protecting our natural resources. We introduce renewable energy sources and alternative fuels into the energy mix where it is viable.
In 2013, Veolia’s solutions prevented 24 million metric tons of global carbon emissions and converted 38 million metric tons of waste into new materials. At the same time, we produced 54 million megawatt hours of energy and provided water and wastewater management services at over 8,500 facilities around the globe.
By coupling the thermal hydrolysis and the anaerobic digestion, Bio Thelys offers better performance than a conventional digestion and optimizes sludge treatment by producing:
Bio Thelys handles all kinds of organic, industrial or municipal sludge and can also handle grease.
Using Bio Thelys process allows to:
Bio Thely is a flexible and safe solution which produces a pasteurised digestate that is compliant with international standards e.g.: EPA class A (UAS) and ADAS Safe Sludge Matrix (UK).
Bio Thelys allows:
Bio Thelys is a solution that guarantees energy and environmental performance, thanks to:
Bio Thelys combines with other Veolia sludge treatment processes such as Athos (hydrothermal oxidation), Pyrofluid (incineration), BioCon (thermal drying), Solia (solar drying) and completes them to offer even more sustainable solutions.
Dehydrated sludge first goes through a batch thermal hydrolysis phase during which steam is injected in reactors operating under specific pressure (9 bar) and temperature (165°C) conditions for approximately 30 minutes.
