The process BioTHELYS® is a pre-treatment for mesophilic anaerobic digestion by thermal hydrolysis. This process has been operated for almost one year in Saumur (France). The current operating conditions are: a temperature of 160–170°C and a hydraulic retention time of circa 30 minutes with concentrated sludge at 12 to 16% dryness. The main effects observed at Saumur on the hydrolysed sludge are the improvement of biodegradability and better viscosity. VS removal in mesophilic anaerobic digester is improved of circa 40 % compared to conventional VM removal on pure biological sludge. Digested sludge after thermal hydrolysis reach 28–30% dryness on centrifuge and are sanitized and stabilised without any nasty odor.
