The versatile PowerRing digester was developed as a modular tank-in-tank system to overcome all challenges of a modern biomethane or biogas plant.
High feedstock and dry matter flexibility
Reduced heat loss and electrical consumption
Allows for easy access to all equipment
Outstanding reliability and operational stability
High total full load hours
High degradation rates and therefore low feedstock consumption
Standard designs ranging from 500 – 5,000 kWth per module
THESE advantages lead to outstanding performance, this is apparent in our many reference plants.
The outer ring, being the primary digester of the PowerRing, is designed to fundamentally improve the mixing efficiency. In contrast to a classic tank design where complete homogenization of the digester volume can present operational challenges, the feedstock in the ring-digester is naturally led through the digester due to its channel-like shape. As a result, the PowerRing is suitable for a wide variety of feedstock including lignocellulosic feedstock with high dry matter that can be used and efficiently processed.
