entec biogas: CSTR-System

The entec biogas-CSTR-Digester is a sealed vertical, cylindrical digester. The mixing of its contents is provided by a centered vertical low-speed agitator which is characterized by its high circulation rate. Thus the digester content is perfectly mixed.

At the same time, the low rotation speed guarantees gentle treatment of the anaerobic microorganisms and due to continuous mixing provides optimal substrate transport for the bacteriological degradation of the organic substances into biogas.

The entec biogas-CSTR-Digester is suitable for the treatment of high solid material, such as bio waste and sludge, as well as for scum developing material. Sediments can be removed easily during operation. It is especially suitable for large scale biogas plants because of construction sizes of up to 6.000 m³.

This digester type has already been applied for the treatment of all kinds of degradable organic wastewater or sludge and waste, such as manure, renewable primary products, municipal bio waste, restaurant and market waste, food industry waste, slaughterhouse waste, sewage sludge.
