Continuous Thermal Hydrolysis Process for sewage sludge pre-treatment. UVa- Aqualogy
The Environmental Technology group of the University of Valladolid and the company Aqualogy, have developed a continuous thermal hydrolysis process for sewage sludge pre-treatment (HTC). This technology permits optimizing the anaerobic digestion, by increasing the biogas production while improving the digester operation as well as the characteristics of the digested sludge.
Since the thermal hydrolysis system is energy self-sufficient, an energy supply is not needed for the pre-treatment unit.
This video shows the evolution of the developed process, from the first laboratory to the current industrial plant that treats the whole amount of secondary sludge generated at the STP of Valladolid.
