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:
|History of anaerobic digester supply since 1973 – standard, proven tank designs||Security of supply based upon proven experience and confidence in the reliability of the product|
|Family of finishes for the optimum choice for product storage||Cost effective containment solutions|
|Modular design allows coatings to be tailored to zones||Reduces project costs|
|Modular design allows modification and extension||Future-proof versatility|
|Lifetime coating requires minimal maintenance||Reduced maintenance costs and downtime revenue losses|
