FBE Coated Tank for a Biogas Plant: Provides reliable,
corrosion-resistant containment for anaerobic digesters.
A Biogas Plant is an energy-producing facility built on the principle of
Anaerobic Digestion , where organic waste is converted into
renewable energy. The core of this process, the anaerobic digester,
is a high-stress environment characterized by intense chemical
attack from high organic loads and the continuous production of
corrosive hydrogen sulfide gas. Successful operation requires a
containment vessel that provides reliable, corrosion-resistant containment to withstand these conditions while maintaining gas-tight
security. The Fusion Bonded Epoxy 
Coated Tank is engineered specifically to be the reliable, corrosion-resistant containment for anaerobic digesters in any Biogas Plant.
The Critical Environment of an Anaerobic Digester
Containment vessels for a Biogas Plant face severe chemical and structural challenges:
Gas Corrosivity 
: Anaerobic digestion generates large quantities of biogas, which
typically contains highly corrosive 
. This gas oxidizes in the tank headspace and above the liquid
line, forming sulfuric acid. The vessel must offer corrosion-resistant containment against this severe, relentless acid attack.
Organic Acid Attack: The feedstock 
breaks down into organic acids ($text{VFA}$s), creating a corrosive
liquid environment that rapidly degrades conventional steel
linings. The tank must provide a reliable, corrosion-resistant barrier.
Gas-Tight Security 
: For the efficient and safe collection of biogas, the digester must
be a gas-tight vessel. The modular structure must be precisely
engineered with robust seals to ensure reliable containment of the flammable gas and prevent air infiltration, which inhibits
the 
process.
High Structural Load: Anaerobic digesters are large-volume reactors that hold dense,
high-solids slurry and often support heavy mechanical mixers. This
requires a reliable and strong vessel capable of managing massive hydrostatic loads.
A successful Biogas Plant demands a solution that offers reliable, corrosion-resistant containment for anaerobic digesters over a long operational life.
The FBE Solution: Optimized for Anaerobic Digesters
Center Enamel’s Fusion Bonded Epoxy Bolted Steel Tanks are
explicitly designed as the reliable, corrosion-resistant containment solution for 
:
Permanent 
and Acid Resistance: The molecularly bonded 
coating is a dense, inert thermoset polymer that provides a
permanent barrier highly effective against the corrosive effects of
and organic acids, making it truly corrosion-resistant containment.
Superior Structural Strength: Constructed from high-tensile, factory-engineered steel, 
tanks offer certified structural strength. They are reliable and robust enough to support the heavy loads of high-solids
digestate and continuous mixing.
High-Integrity Gas Sealing: The precision of the bolted panel design, combined with
chemical-resistant sealants, creates a guaranteed gas-tight vessel.
This ensures reliable containment and maximum recovery of the high-value biogas.
Rapid, Cost-Effective Deployment: The modular design ensures extremely fast on-site assembly,
minimizing the total cost and construction time. This feature makes
the FBE Coated Tank a cost-effective and reliable choice for setting up or expanding a Biogas Plant.
Versatility in AD Stages: 
tanks are ideal not only for the main digester but also for
pre-treatment equalization tanks, post-digestion storage, and
digestate dewatering stages, ensuring corrosion-resistant containment throughout the entire process.

Longevity and Biogas Plant Efficiency
The longevity of the digester directly affects the profitability of
a Biogas Plant. The FBE Coated Tank contributes to higher overall plant efficiency:
Minimized Downtime: The permanent, corrosion-resistant lining drastically reduces the need for relining or internal
maintenance, ensuring the digester remains online and generating
energy.
Process Stability: The inert 
surface and gas-tight design contribute to process stability by
maintaining the ideal, reliable environment for the methanogenic bacteria.
Reduced Lifecycle Cost: By combining the low initial construction cost with minimal
long-term maintenance, the 
tank provides a high return on investment, cementing its status as
a reliable asset.
