Why Choose GFS Tanks for Anaerobic Digestion?

GFS tanks, also known as Glass-Lined Steel (GLS) tanks, offer a high-performance containment solution for anaerobic digestion systems. Unlike traditional concrete or welded steel tanks, GFS anaerobic digestion tanks feature a unique fusion of high-strength steel and an inert glass coating, delivering unmatched advantages:

1. Unrivaled Corrosion Resistance

Anaerobic digestion processes generate highly corrosive environments due to the presence of hydrogen sulfide (H₂S), ammonia, and organic acids. Our GFS tanks provide superior resistance against chemical and biological corrosion, ensuring long service life and minimal maintenance compared to epoxy-coated or concrete tanks.

2. Airtight Sealing for Optimal Biogas Production

Efficient biogas production relies on an airtight and stable environment. Center Enamel’s GFS anaerobic digestion tanks feature gas-tight designs with options for double-membrane roofs or aluminum dome covers, ensuring maximum methane retention and process efficiency.

3. Modular and Expandable Design

GFS anaerobic digestion tanks are bolted structures, allowing for fast installation and easy expansion. The modular design makes them ideal for new projects, capacity upgrades, or plant retrofits, offering flexibility and cost-effectiveness.

4. High Mechanical Strength and Structural Stability

Manufactured in compliance with AWWA D103-09, EN 28765, NSF/ANSI 61, and ISO 9001 standards, Center Enamel’s GFS tanks are engineered for high structural integrity. They withstand extreme weather conditions, seismic activity, and internal pressure variations, ensuring reliable long-term operation.

5. Fast Installation & Low Maintenance

The prefabricated panels are manufactured at our facility and then assembled on-site using a bolted connection system, significantly reducing construction time and costs. Unlike concrete tanks, which require curing time and regular surface maintenance, GFS tanks offer a low-maintenance solution with exceptional longevity.

Applications of GFS Anaerobic Digestion Tanks

Center Enamel’s GFS anaerobic digestion tanks are widely used in various industries, including:

Biogas Plants – Organic waste-to-energy conversion for sustainable power generation.

Municipal Wastewater Treatment – Efficient sludge digestion for enhanced waste management.
