Anaerobic Digestion Tank

Anaerobic Digestion Tanks are critical biological treatment units used in wastewater treatment systems to break down organic matter in the absence of oxygen. Bolted tank construction provides a reliable and adaptable solution for anaerobic digestion applications in municipal and industrial facilities.

This page focuses exclusively on anaerobic digestion tank applications, independent of tank material or structural product category.

Role of Anaerobic Digestion in Wastewater Treatment

Anaerobic digestion is employed to reduce organic load and stabilize wastewater or sludge through controlled biological processes. Anaerobic digestion tanks provide the enclosed environment required for effective microbial activity.

Typical functions include:

• Reduction of biodegradable organic content
• Stabilization of wastewater or sludge streams
• Support of downstream treatment processes
• Improvement of overall plant efficiency

Engineering Requirements for Anaerobic Digestion Tanks

Anaerobic digestion tanks must maintain controlled internal conditions to support biological activity. Bolted tanks are engineered to meet these requirements while allowing flexibility in system integration.

Key engineering considerations include:

• Structural integrity under continuous operation
• Reliable sealing to maintain anaerobic conditions
• Compatibility with mixing and circulation systems
• Integration with gas handling interfaces
