Dranco - Model BES-CSTR -Process Technology
DRANCO nv offers the design and construction of wet completely mixed digesters. These digesters work at a low total solids-content and can be used as main digesters, or as post-digesters (e.g. following a DRANCO-FARM or BES-Plugflow digester).
DRANCO nv offers continuously stirred-tank reactors. This conventional digester concept was adjusted according to the high DRANCO standards concerning reliability and safety. The BES-CSTR digester was developed to treat rather wet agro-industrial waste, energy crops, crop residues, manure and food waste.
DRANCO nv uses this type of technology for clean and wet organic feedstocks such as energy crops, agro-industrial residues or food waste. The BES-CSTR is a continuously stirred tank-reactor with a gas storage on top.
BES-CSTR characteristics
- round digester in concrete
- total solids content between 2 and 12% in the digester
- mesophilic or thermophilic operating temperature
- easy replacable stirrers
- modular concept
The BES-CSTR process has some significant advantages:
- simple design
- short construction period
- optimal heat- and material distribution inside the digester
- limited height
- efficient degassing inside the digester
- large digester volumes possible
