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 utilized for mesophilic digesters, thermophilicdigesters, pasteurising digesters and enhanced enzymichydrolysis (EEH) digesters amongst various other processesand applications.

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

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

Biogas produced can be cleaned and introduced directly intothe grid, or converted into electricity in combined heat andpower engines (CHP). This also gives the opportunity togenerate 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 accommodate variousaspect ratios, process pressures and temperatures to suit avariety of AD processes, designs and applications as specifiedby your process designer.

Glass-Fused-to-Steel is not only utilized for the tank walls butalso in the roofs on tanks such as digesters. This gives thehigh degree of protection of Glass-Fused-to-Steel throughouta digester, especially in the highly aggressive gaseous zone.

These roofs are structurally designed to allow for localenvironmental loading and can also support centrally

mounted mixer systems.

Additionally, Glass-Fused-to-Steel tankscan also be used for biogas storage

by incorporation of doublemembrane covers.

The combination of Permastore’s inert Glass-Fused-to-Steelfinishes, combined with the strength of steel and the flexibilityof modular construction give significant benefits over othertypes of digester structures. These include:
