Motivation for anaerobic sludge stabilization:
Roediger® is a brand of Aqseptence Group GmbH
The digestion process:
Freely suspended lances inject the gas above the reactor floor, allowing maximum flexibility in the shape and design of the digester.
Maintenance of the lances can be carried out during operation, emptying of the digester is not necessary.
The maximum achievable degree of organic matter degradation (oTS) depends on the type and quality of the sludge and the intensity of the digestion:
55 – 70% oTS degradation for primary sludge
35 – 50% oTS removal for waste activated sludge
The degradability also depends on the pre-treatment, e.g. by hydrolysis, the sludge age, the number of digestion stages and the process quality.
