Waste-to-Energy Biogas Storage Tanks

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

The bioenergy industry is growing around the world as an environmentally acceptable renewable energy source generated from biomass. Biofuel use can reduce emissions of greenhouse gases, lower the demand for fossil fuels and is often supported by government subsidies. EA Tanks has capabilities across all stages of the bioenergy storage tank lifecycle from permitting, commissioning and planning, to construction, testing, inspection, proactive maintenance and remediation solutions. 

EA Tanks's Anaerobic Digesters offer bioenergy contractors and end-users significant benefits over welded and concrete structures. 

  • Our tanks never need painting and don't rust, corrode or chalk. Our unique tank construction utilizes the smallest construction footprint with little disturbance to the surrounding environment. 
  • Our bolted tanks are constructed in 1/3 of the time it takes to build concrete and welded tanks and can be expanded to accommodate future capacity requirements. 
  • Our coatings are applied in the factory which means minimized construction delays due to weather compared to concrete and field-applied coatings. 
  • Our bolted tanks are constructed at ground-level using a jacking system that elevates the structure to install the panels without the need for expensive cranes, scaffolding and equipment. 
  • Our bolted tanks can be assembled in even the most remote sites, without large staging areas, during any season of the year. 

Glass-Fused-to-Steel tanks are utilised for mesophilic digesters, thermophilic digesters, pasteurising digesters and enhanced enzymic hydrolysis (EEH) digesters amongst various other processes and applications.

Almost any organic waste can be digested, opportunities have developed to utilise food processing waste, domestic waste and restaurant waste.  Increasingly combinations of waste streams are being processed along with co-digestion of municipal sludge effluent and farm waste such as animal slurry to generate “green” renewable energy.

Biogas produced can be cleaned and introduced directly into the grid, or converted into electricity with generators using 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.

Modular design allows the flexibility to accommodate various aspect ratios, process pressures and temperatures to suit a variety of AD processes, designs and applications as specified by your process designer.

Glass-Fused-to-Steel is not only utilised for the tank walls but also in the roofs on tanks such as digesters.  This 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 covers.

The combination of our 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.
