Fusion Bonded Epoxy Tank for Fermentation Wastewater Treatment:
Built to withstand the acidic and high-strength conditions of
fermentation waste.
Fermentation wastewater treatment encompasses managing aggressive effluent from diverse industries,
including alcohol production, pharmaceuticals, brewing, and certain
chemical processes. This wastewater is consistently characterized
by high organic strength and, most critically, acidic conditions resulting from the production of volatile fatty acids. Containing
this corrosive mixture requires a vessel built to withstand the acidic and high-strength conditions of
fermentation waste over decades of service. The Fusion Bonded Epoxy (FBE) Tank is engineered to meet these extreme structural and chemical
demands, providing the necessary resilience for anaerobic and
aerobic biological treatment.
The Aggressive Nature of Fermentation Waste
Containment vessels in fermentation wastewater treatment are subjected to a constant, two-pronged attack: chemical and
structural:
Corrosive Acidic Conditions: The breakdown of high concentrations of sugars and starches
inherent in fermentation waste generates organic acids (like acetic and lactic acid). This
creates persistently acidic conditions (low 
) that severely and rapidly corrode unprotected metal and
chemically attack concrete linings. The tank must be built to withstand this relentless chemical stress.
High-Strength Organic Load: The effluent's high 
dictates the need for large-volume reactors with extended retention
times. This places immense hydrostatic pressure on the vessel
structure, requiring a tank built to withstand heavy load conditions and support substantial mixing or aeration
equipment.
Biogas Corrosivity: When fermentation waste is treated anaerobically, the resulting biogas often contains
hydrogen sulfide (
). This gas, when dissolved or in the headspace, creates a
secondary source of aggressive corrosion (sulfuric acid),
necessitating a permanent, gas-tight, and highly corrosion-resistant lining.
High Temperature and Volume Fluctuation: Batch processes often lead to discharges at elevated temperatures
and fluctuating volumes, demanding a containment solution with
robust thermal stability and structural resilience to absorb
hydraulic shock.
A sustainable solution must be structurally sound and chemically
resilient, specifically built to withstand the acidic and high-strength conditions of
fermentation waste.
The FBE Solution: Withstanding Acidic and High-Strength Conditions
Center Enamel’s Fusion Bonded Epoxy Bolted Steel Tanks are
explicitly engineered to address the combined challenges of high
load and corrosion in fermentation wastewater treatment:
Permanent Acid Protection: The FBE coating is a dense, thermoset polymer that is molecularly
bonded to the steel substrate. This inert, high-performance barrier
provides superior, permanent protection against the low 
and organic acids characteristic of acidic conditions, ensuring the steel remains entirely protected.
Structural Integrity for High Loads: Constructed from high-tensile, factory-engineered steel, FBE tanks
are inherently robust. They are built to withstand the significant hydrostatic pressure exerted by the heavy,
high-strength liquid, as well as the mechanical stress from the
heavy-duty mixers and internal process equipment essential for
treating fermentation waste.
Optimal for Anaerobic Digestion: The FBE tank's inherent gas-tight design, combined with its
resistance to 
and acidic liquid, makes it the ideal, high-integrity vessel for anaerobic reactors, which are commonly used to convert fermentation waste into renewable biogas.
Rapid, Cost-Effective Deployment: The modular, bolted construction allows for significantly faster
construction than concrete, minimizing downtime and quickly
establishing treatment capacity necessary to handle the large
volumes of fermentation waste.
Long-Term Reliability: The durability of the FBE lining guarantees a long service life
with minimal maintenance, reinforcing its value as a reliable, corrosion-resistant core built to withstand the toughest conditions.
