Digester Mixers
Effective mixing of the anaerobic digester contents is important for process
stability. Mixing maximizes gas production and minimizes scum and foam
formation. Additionally, it prevents solids deposition in the digester, which can
reduce the active volume of the digester and result in expensive removal costs.
Doda offers a full range of mixing systems from primary digester, secondary
digester through to final higher pressure gas storage tanks. All mixers can
be easily adjusted in mixing angle and depth to suit changeable tank levels.
Models range from the BGS 80 which is often used in secondary fermentation
tanks for smooth constant homogenization through to the BGS 500 for
applications in primary tanks where the materials require high-speed agitation
to get the fermentation process moving rapidly

BGS 80
- Primary and secondary digester applications—strong, slow yet gentle and constant mixing usess
- For use in higher dry matter (DM) applications with heavy workloads on the mixer
- 1600mm propeller
- 22KW motor
- Standard lengths 3.6M & 4.6M (other sizes available)
BGS 200
- Primary, secondary or final digester applications—strong and constant mixing uses
- For use in lower dry matter (DM) digestate applications
- 1200mm propeller
- 6.5M length (other sizes available)
- 22KW motor with toothed belt drive without gearbox
BGS 500
- Initial intake reception pit applications—strong and aggressive mixing applications
- Also used in final storage facilities for agitation
- For use in lower dry matter (DM) digestate applications where chopping of media is required
- 600-840mm propeller
- 6.5M length (other sizes available)
- 15 or 18KW motor with toothed belt drive without gearbox
Advantages
- Customizable and can be fitted to any existing or new digesters
