Biogas / Anaerobic Digestion

Permastore’s history of anaerobic digestion (AD) tanks goes back to the early 1970’s, and the Company’s experience has expanded considerably over the decades. Glass-Fused-to-Steel tanks are utilised for:

  •     Mesophilic digesters
  •     Thermophilic digesters
  •     Pasteurising digesters
  •     Enhanced enzymic hydrolysis (EEH) Digesters

Glass-Fused-to-Steel (Glass-Lined-Steel) is not only utilised for the tank walls but also in the roofs on tanks such as digesters.  This is gives the high degree of protection of Glass-Fused-to-Steel throughout a digester, especially in the highly aggressive gaseous zone.

These roofs are structurally designed to allow for local environmental loading and can also support centrally mounted mixer systems.

Additionally, Glass-Fused-to-Steel tanks can also be used for biogas storage by incorporation of double membrane roofs.

The combination of Permastore’s inert Glass-Fused-to-Steel finishes, combined with the strength of steel and the flexibility of modular construction give significant benefits over other types of digester structures.  These include:

Feature Benefit
