This webinar looks at two utilities' experience using thermal hydrolysis for sewage sludge treatment and improved biosolids management. Different aspects will be showcased, such as the overall technology principle, drivers, project execution, lessons learned and project outcomes, with relevant case study examples from these utilities. An emphasis on operational experience will also be shared by the utilities.
