Biogas / Anaerobic Digestion
Fusion’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 utilized for:
- Mesophilic digesters
- Thermophilic digesters
- Pasteurizing digesters
- Enhanced enzymic hydrolysis (EEH) Digesters
In the industrial sector using anaerobic digestion to create biogas is increasingly recognised as a valuable method to utilize waste streams to create renewable energy.
Since any organic waste can be digested, opportunities have developed to utilize food processing waste, domestic waste and restaurant waste. In addition to this, combinations of waste streams can be processed incorporating municipal sludge effluent and farm waste such as animal slurry to generate this green energy.
Biogas produced can be cleaned and used directly, or converted into electricity in combined heat and power engines (CHP). This also gives the opportunity to generate heat energy in the form of hot water.
At the end of the process the digested material can be considered for use as fertilizer, which increases the potential revenue streams.
Glass-Fused-to-Steel (Glass-Lined-Steel) is not only utilized 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 Fusion’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|
