UASB Anaerobic Tank Safety And Maintenance

Leak and Explosion Prevention
Biogas is mainly composed of CH₄ (70%–80%) and carries an explosion risk. The system must be strictly sealed, and gas leaks should be regularly checked.

Biogas emissions should be burned through a flare and must not be released directly into the atmosphere.

Structural Safety (especially for assembled tanks)
The foundation must not settle beyond permissible limits, and bolt connections should be tightened according to the specified torque to prevent fatigue fractures.

Damage to enamel or anti-corrosion coatings can lead to hidden corrosion, so a comprehensive inspection every 3–5 years is recommended.
