Most cost effective solution tomeet customers’ needs

Permastore’s history of anaerobic digestion (AD) tanksexceeds 40 years, and the Company’s experience hasexpanded considerably over the decades. Glass-Fused-to-Steel tanks are utilised for mesophilic digesters,thermophilic digesters, pasteurising digesters andenhanced enzymic hydrolysis (EEH) digesters amongstvarious other processes and applications.

In the industrial sector using anaerobic digestion to createbiogas is increasingly recognised as a valuable method toutilise waste streams to create renewable energy.

Almost any organic waste can be digested, opportunitieshave developed to utilise food processing waste, domesticwaste and restaurant waste. Increasingly combinations ofwaste streams are being processed along with co-digestionof municipal sludge effluent and farm waste such as animalslurry to generate “green” renewable energy.

Biogas produced can be cleaned and introduced directlyinto the grid, or converted into electricity in combined heatand power engines (CHP). This also gives the opportunityto generate heat energy in the form of hot water.

At the end of the process the digested material can beconsidered for use as fertilizer, which increases the potentialrevenue streams.

Modular design allows the flexibility to accommodatevarious aspect ratios, process pressures and temperaturesto suit a variety of AD processes, designs and applicationsas specified by your process designer.

Glass-Fused-to-Steel is not only utilised for the tank wallsbut also in the roofs on tanks such as digesters. This givesthe high degree of protection of Glass-Fused-to-Steelthroughout a digester, especially in the highly aggressivegaseous zone.

These roofs are structurally designed to allow for localenvironmental loading and can also support centrallymounted mixer systems.

Additionally, Glass-Fused-to-Steel tanks can also be usedfor biogas storage by incorporation of

double membrane covers.

The combination of Permastore’s inert Glass-Fused-to-Steelfinishes, combined with the strength of steel and theflexibility of modular construction give significant benefitsover other types of digester structures. These include:
