GFS Biogas Digester Tanks | Anaerobic Digester Tanks

Anaerobic digester Tanks ( GFS Biogas digester tanks ) are air-tight tanks with different configurations. An Anaerobic digester tank is a liquid storage tank that is used for digestion of stored complex slurry/wastewater into simpler compounds and in turn, releases gases which are then either used as fuel or are exposed to the environment under permissible limits. Complex slurry/sludge/wastewater includes Blackwater, Greywater, Brownwater which includes Sewage, farm wastes, food waste, human waste, municipal waste, industrial waste, etc. are used as waste whose digestion takes place.

There are two key processes: mesophilic and thermophilic digestion which are used for digestion and are dependent on temperature.

Mesophilic Digestion – GFS Biogas Digester Tanks

Mesophilic digestion takes place optimally around 30 to 38 °C or at ambient temperatures between 20 and 45 °C, where mesophiles are the primary microorganism present. 

Thermophilic Digestion – GFS Biogas Digester Tanks

Thermophilic digestion takes place optimally around 49 to 57 °C or at elevated temperatures up to 70 °C, where thermophiles are the primary microorganisms present.

The microorganisms in the sludge layer degrade organic compounds. As a result of the above process, gases (methane and carbon dioxide) are released. The most common type of Digestor tanks used in Industry are UASB tanks.

Rostfrei‘s Glass fused to Steel tanks are extensively used in digester tanks Applications in Agricultural sectors and ETP Plants and we provide Turnkey Solution for Manufacturing and Installation of digester tanks including Gas Collection Roofs, arrangements for installing Heat Exchangers inside the tanks.

Glass Fused Steel Digester Tanks

Use of Glass fused Steel tanks in digester tanks have many advantages over conventional tanks and are listed as below:

  • Accessibility to install multiple accessories like heat exchangers, agitators, tank insulation, etc.
  • Construction time reduction from a year in conventional tanks to several months in Glass fused tanks.
  • No Reaction with the Tank walls.
  • Less Maintenance in comparison with conventional tanks.
  • Accessories modification as per requirement.
