Greatario delivers proven, purpose-built storage tanks and cover systems designed specifically for biogas and anaerobic digestion applications. These environments are among the most demanding in industrial and municipal infrastructure—requiring materials, coatings, and structural designs that can withstand corrosive conditions, pressure fluctuations, and mechanical loads over decades of operation.
Anaerobic digesters are not forgiving systems. Choosing the wrong tank or cover solution can compromise biogas production, introduce serious safety risks, and lead to premature system failure. Selecting the right storage solution from the outset is one of the most critical decisions a biogas facility owner or process developer will make.
Biogas digesters operate under harsh chemical and physical conditions. The interaction between digestate, vapor zones, gas pressure, and mixing equipment places constant stress on tank materials.
The right tank and the right coating technology are essential to:
Greatario provides a full range of coating and material technologies to match the specific demands of each digester application, including:
This flexibility allows each system to be engineered—not standardized—based on process conditions.
Selecting the correct cover solution is equally critical to digester performance and safety. Cover design must account for:
Greatario offers multiple digester cover options, giving owners and engineers the design flexibility to select the best solution for their process requirements.Â
Each cover system is engineered to integrate seamlessly with the selected tank material and coating system.
Greatario’s factory-coated, bolted tank systems are modular by design—allowing installation in locations where traditional welded tanks are impractical or disruptive.
This approach supports both new builds and retrofits in operating facilities.
Digestate storage presents its own challenges due to the highly corrosive nature of the material.
Greatario provides expert guidance on selecting the optimal storage solution—whether glass-fused-to-steel or epoxy-coated steel—to ensure:
Glass-fused-to-steel (GFS) tanks combine the strength of steel with the corrosion resistance of glass, permanently fused at high temperatures.
This results in one of the most resilient and cost-effective storage systems available for biogas, biomass, wastewater, and digestate applications.
Whether you’re storing potable water, wastewater, or biogas, Greatario’s glass-fused-to-steel tanks deliver proven durability and unmatched lifetime value. With more than 60 years of field performance and coast-to-coast project experience, Greatario builds storage infrastructure designed to stand the test of time—and climate.
Greatario’s bioenergy storage solutions include industry-leading roof and cover systems engineered for biomass, biogas, and digester applications. Available roof options:
Each system is designed to address corrosiveness, mixer loads, internal pressure and vacuum, and ancillary equipment requirements.
Greatario is the sole Canadian distributor of the HydroMix System from EBARA HG.
The HydroMix® System offers a cost-effective and reliable solution for wastewater and digester mixing and is:
A biogas digester tank is used to contain organic material undergoing anaerobic digestion, where microorganisms break down waste to produce biogas and digestate.
Digesters expose tanks to corrosive liquids, aggressive gases, pressure fluctuations, and mechanical loads from mixers—making material and coating selection critical.
Glass-fused-to-steel is widely considered one of the best options due to its corrosion resistance, long service life, and predictable maintenance costs. Epoxy-coated steel and stainless steel may also be appropriate depending on the application.
The cover must safely manage pressure, vacuum, gas containment, and equipment loads. An improperly designed cover can compromise safety and system performance.
Yes. Greatario provides storage tanks, covers, and mixing systems for both new biogas facilities and upgrades to existing systems.
With proper design and maintenance, glass-fused-to-steel tanks can provide decades of service life with minimal corrosion-related issues.
