Unmatched Corrosion Resistance for Sludge Storage

Sludge generated during wastewater treatment contains a mix of organic and inorganic materials that can be highly corrosive to conventional storage tanks. GFS tanks feature a fused glass coating bonded to a steel substrate at high temperatures (820°C–930°C). This creates a non-porous, chemically resistant barrier that:

Prevents corrosion from acids, alkalis, and sulfates in sludge.

Provides superior abrasion resistance.

Ensures long-term durability in harsh environments.

Key Features of GFS Sludge Holding Tanks

1. High Durability

The fusion of glass and steel results in a tank that is both strong and resistant to wear and tear. This makes it ideal for withstanding the challenging conditions of sludge storage.

2. Modular Design for Rapid Installation

GFS tanks are delivered as prefabricated panels, allowing for quick and efficient assembly on-site. This modular design reduces construction time and project costs significantly.

3. Leak-Proof Performance

To ensure environmental safety, GFS tanks are equipped with advanced sealants and precision bolted connections, creating a completely watertight structure.

4. Low Maintenance Requirements

The glass-coated interior surface prevents sludge buildup and resists chemical reactions, reducing cleaning and maintenance costs over the tank’s lifespan.

5. Environmentally Friendly Solution

The materials used in GFS tanks are recyclable, making them an environmentally sustainable option for sludge storage.

6. Versatile Design Options

GFS tanks come in various sizes and configurations, tailored to meet the specific requirements of municipal sewage treatment plants, industrial effluent systems, and agricultural wastewater facilities.

Applications of GFS Sludge Holding Tanks in Wastewater Treatment

Primary Sludge Storage: Holding sludge before further treatment processes.

Secondary Sludge Storage: Temporary storage for biological sludge from secondary treatment.

Equalization Tanks: Balancing flow and load for consistent sludge processing.

Digestion Tanks: Storing sludge for anaerobic digestion and biogas generation.
