La planta de digestión del organismo de agua de Reest en Wieden garantiza que toda la planta de tratamiento de aguas residuales, incluida la digestión de lodos, funcione con neutralidad energética. El sistema permite reducir el coste del tratamiento de los lodos y recuperar las materias primas.

It’s the first system in the Netherlands that digests sludge in a thermophilic digester, followed by a mesophilic digester. With this combination, a higher degradation is achieved in comparison with conventional technology for sludge digestion. During multiple tests, the increased sludge digestion is demonstrated.

HoSt is responsible for the design, construction and commissioning of the plant and also provides for process technical guidance during the warranty period of 1 year.
