Advantages of Glass-Fused-to-Steel Tanks for Sludge Storage

1. Unmatched Durability

The fusion of glass and steel creates a durable, non-porous surface that provides:

Superior Corrosion Resistance: Withstands the aggressive chemical environment of digested sludge and waste activated storage.

Long Lifespan: Engineered to perform for decades with minimal maintenance.

2. Modular and Scalable Design

Our bolted tank construction allows for rapid installation and scalability, making it suitable for projects of varying capacities. Tanks can be easily expanded or relocated as operational needs change.

3. Compliance with International Standards

Center Enamel GFS tanks are designed and manufactured to meet or exceed global standards, including:

AWWA D103-09

EN ISO 28765

NSF/ANSI 61

Membrane Roofs: The Perfect Solution for Sludge Storage Tanks

1. Airtight Design

The membrane roof creates a gas-tight seal, preventing the escape of odors and gases generated during sludge digestion and storage.

2. Biogas Collection

For facilities engaged in biogas recovery, the membrane roof efficiently captures biogas, enabling its use as a renewable energy source.

3. Weather Resistance

Designed to withstand extreme weather conditions, including high winds and heavy snow loads, the membrane roof ensures uninterrupted operation.

4. Lightweight and Flexible

The roof’s lightweight construction reduces structural load while its flexibility accommodates internal pressure fluctuations, ensuring safety and reliability.

Applications of GFS Tanks with Membrane Roofs

1. Digested Sludge Storage

Effective storage of digested sludge resulting from anaerobic digestion processes in wastewater treatment plants.

Gas-tight storage solution to contain and process by-products.

2. Waste Activated Storage

Storage of activated sludge from aeration processes in biological treatment facilities.

Reliable containment with resistance to high humidity and aggressive chemical environments.

3. Biogas Recovery Systems

Integration with biogas recovery systems for renewable energy generation.

Gas-tight sealing to prevent losses and ensure safety.
