Veolia Water has developed during these last years its own THP (Thermal Hydrolysis Process) named BIOTHELYS® in order to enhance MAD (mesophilic anaerobic digestion) of municipal or industrial sludge. The first reference BIOTHELYS® has been installed at Saumur in France, an extended aeration biological nutrient removal facility, and commissioned in April 2006. The thermal hydrolysis of dewatered sludge is realised by steam injection at a temperature of 160°C for duration of circa 30 minutes. The THP reactors are paired in order to recover flash steam and heat sludge economically. The MAD of hydrolysed sludge is done within a HRT of 15 days and reaches volatile reduction of more than 45% on extended aeration biological sludge. BIOTHELYS® turns the MAD of extended aeration biological sludge into a very attractive solution while producing green energy with biogas. MAD is thus no more only reserved for mixed sludge but also for pure biological sludge when using THP.

Hydrolysis Temperature

In 110~190°C for 15~75min excess sludge thermal hydrolysis test, investigated the dissolution rate of the volatile suspended solids, Sludge SCOD, TCOD concentration change in composition of organic acids in the supernatant, and analysis the improvement of the anaerobic digestion performance. The results show that, with the increase of thermal hydrolysis temperature and extension of time, sludge supernatant on SCOD, VFA rising. At 190 °C, 75min conditions, SCOD, VFA reached the maximum 6674mg / L2630mg/ L; Sludge organic solids dissolved and the release of COD, etc. mainly in the first 45 min to complete, little change after 45min. When thermal hydrolysis temperature between 90~170°C, anaerobic digestion performance increase with temperature rise, When the temperature is higher than 170 °C, the sludge anaerobic digestion performance begins to decline.
