Product Details
Types of Enamel Assembled Tanks & Their Ideal Applications
A. Standard Enamel Tanks (For Water & Wastewater)
Description: Tanks constructed from standard-thickness enamel panels, designed for the storage and treatment of water, municipal wastewater, and industrial effluent with moderate chemical loads.
Ideal Applications:
o Municipal drinking water storage
o Process water and rainwater collection tanks
o Primary and secondary wastewater treatment clarifiers and aeration tanks
o Equalization and storage basins
B. Reinforced/Heavy-Duty Enamel Tanks (For Anaerobic Digestion & Agitation)
Description: Built with thicker-gauge enamel steel and reinforced structural supports to withstand the aggressive internal environment of anaerobic digestion, including high loads, pressure fluctuations, and mechanical agitation.
Ideal Applications:
o Anaerobic digesters for biogas production (agricultural, WWTP, co-digestion plants)
o Tanks with submersible mixers or gas lances
o Fermentation tanks in bio-industries
o Storage of sludges and high-solid content materials
C. Specialty Chemical Tanks
Description: Utilizes high-resistance enamel formulations and specialized seals designed to handle extreme pH levels and specific aggressive chemicals.
Ideal Applications:
o Storage of acids, alkalis, and brines
o Chemical dosing and mixing tanks in industrial processes
o Leachate storage and treatment at landfills

Glossary:
• Enamel (Vitreous Enamel): A glass-based coating fused to steel at high temperature, creating an inert, non-porous, and ultra-durable surface.
• EPDM: Ethylene Propylene Diene Monomer, a synthetic rubber gasket with excellent weather resistance.
• PTFE: Polytetrafluoroethylene (Teflon® ), a high-performance, chemically inert gasket material.
• HDPE: High-Density Polyethylene, often used for tank floors and liners.
• m ³: Cubic meters.
