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.
