Thelys™

Sludge treatment using thermal hydrolysis

Thelys™ is a thermal hydrolysis process used to treat municipal or industrial sludge generated by treatment works.

The hydrolysed sludge is then digested using anaerobic digestion.

Thelys™ optimises the anaerobic digestion phase by increasing the quality of biodegradable organic matter and hence reducing the size of digester required.
