Delfland Investigates Torwash Technology for Sludge Treatment at De Groote Lucht Wastewater Facility
Hoogheemraadschap van Delfland is conducting research on the Torwash technology for sludge processing at the De Groote Lucht wastewater treatment facility in Vlaardingen. This investigation will determine the effectiveness and costs of the method, which operates under high temperature and pressure to significantly reduce sludge volume and recover resources such as biogas.
Other water boards, including Zuiderzeeland and Aa en Maas, have previously conducted successful small-scale tests. Delfland's study aims to provide insights into energy consumption and efficiency on a larger scale, with results anticipated by mid-2027.
A budget of approximately 3 million euros is allocated for this research, supported by over 1.3 million euros from Torwash and STOWA. The new Vergulde Hand facility is planned to accommodate a larger capacity by 2030, potentially integrating Torwash if proven effective.
