Biological sludge reduction plant
Biothelys™
Veolia Water STI
Biothelys™ is a complete solution for reducing the quantity of sludge at source and applies to both municipal and industrial sludge.
It is based on the Thelys™ hydrolysis process, which improves the biodegradability of organic matter, so that it can subsequently be subjected to aerobic or anaerobic biological treatment. It fits perfectly into wastewater treatment processes by operating in tandem with the sludge recirculation system.
