The Role of Clarification Tanks in Water Treatment

Clarification tanks are key components in municipal and industrial water treatment facilities. They enable solids settling, separation of silt and suspended particles, and improve water clarity before further treatment stages. Requirements for tanks used in clarification include:

• Resistance to corrosion and chemical attack from coagulants, flocculants, and natural water constituents
• Smooth internal surfaces to facilitate effective sludge settling and discharge
• Structural integrity to support large volumes with regular hydraulic loading
• Ease of maintenance and cleaning to minimize downtime
• Compliance with international water treatment standards
• Modularity and scalability to fit various plant sizes and throughput needs

Traditional concrete or coated steel tanks often face challenges such as surface degradation, cracking, and contamination risks over time.

What is Glass-Fused-to-Steel (GFS) Technology?

Center Enamel’s GFS technology involves a process where powdered glass is thermally fused to hot-rolled steel plates at high temperatures (around 820°C to 930°C), forming a cohesive, vitreous enamel coating. This coating endows the tank panels with a smooth, non-porous, chemically inert surface on both interior and exterior sides.

Advantages of GFS Clarification Tanks by Center Enamel

• Outstanding Corrosion Protection: The chemically fused glass coating prevents rust and chemical degradation typically caused by water treatment chemicals.
• Smooth Surface Enhances Performance: Non-porous interior limits bacterial growth and sediment adhesion, improving sludge settling and tank cleaning.
• Long-Term Durability: Reduced maintenance costs as tanks maintain structural integrity and coating stability over decades.
• Modular, Flexible Design: Bolted assembly allows for customized sizing, phased installation, and easy retrofitting or expansion.
• Environmental Compliance: Designed to meet stringent water treatment and environmental health standards globally.
• Easy to Clean and Maintain: Reduced fouling and surface wear facilitate periodic cleaning, minimizing operational downtime.
• Robust Mechanical Strength: Steel substrate provides resistance to hydraulic and environmental loads, ensuring safe operation.

Industry Applications

• Municipal Water Treatment Plants: Efficient removal of turbidity and suspended solids during potable water clarification.
• Industrial Wastewater Treatment: Clarification tanks designed for process wastewater, including chemical, food, and textile industries.
• Sludge Thickening and Dewatering: Enhancing sludge settling as part of solid-liquid separation processes.
• Environmental Remediation Facilities: Treating contaminated groundwater or surface water with particulate removal.
