SEWAGE SLUDGE TREATMENT FROM THE SAN ADRIÁ DEL BESÓS WASTE WATER TREATMENT PLANT.
The project consists of a modification in the sludge drying system originated at the Besos waste water treatment plant.
Metrofang installed a new thermal drying system with a low temperature process (<80 °C). The system has an evaporating capacity of 16,000 l / h in 4 separate lines.
The sticky sludge from the water treatment plant is difficult to manage. Sludge drying aims to improve waste handling and processing characteristics. Furthermore, this sludge drying process greatly limits the heavy volatile harmful emissions.
The required caloric intake is ensured through a closed hot water loop from the block and the exhaust gases from the cogeneration engine.
