Description

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 & Secondary Digester – Strong, slow yet gentle and constant mixing uses
For use in Higher dry matter (DM) applications with heavy workloads on the mixer
1600m 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
1200m 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
600-840m propeller
6.5M length (other sizes available)
15 or 18KW motor with toothed belt drive without gearbox

Hydraulic Angle Adjustment System

Tilting can be done automatically with a level sensor and controlled by the plants’ control system or manually with a hydraulic hand pump. The tilting system is also fitted with anti-vibration pads.

Integrated Tank-Mounted Frames

Mounting frames for each mixer type can be manufactured to be “cast” into the tank wall and can be made to fit steel tanks as well.
