Biogas FlaresLogical Waste Foam Trap
Effective Foam Management for Biogas Systems
The LogicalWaste Foam Trap (LFT) offers a proven, locally supported solution to one of the most common biogas plant issues, foam carryover. The LogicalWaste Foam Trap is purpose-built to remove foam and sludge from biogas pipelines, protecting downstream equipment and maintaining plant performance. Designed for gas flows up to 500 Nm³/hour, the LFT-500 is suitable for all types of anaerobic digesters and offers automatic foam detection, removal, and system protection.
With its automatic operation, simple design, and durable construction, it delivers long-term reliability with minimal operator intervention.
Key Advantages
- Automatic Foam Removal
Foam is detected and flushed away automatically, preventing blockages and damage. - Reliable Water Seal
Maintains system integrity and prevents biogas release. - Simple & Low Maintenance
Automatic spray cycle keeps the system clear and maintain the water seal. - High Safety Design
Overflow system prevents vacuum collapse and allows safe venting. - Local Support
Designed and built locally for fast service and parts availability.
How it Works
The incoming gas enters tangentially, creating a swirl that slows flow and drops foam/sludge to the base. Dual spray nozzles in the upper chamber periodically wash down foam into the cone. Excess foam and water exit through the overflow pipe to the sludge tanks. A foam sensor triggers water spray when foam is detected, ensuring uninterrupted operation.
