The Role of RO Water Storage Tanks

RO purification systems typically produce water at a slower rate compared to instantaneous demand. RO water tanks serve as a buffer, accumulating purified water for on-demand use, ensuring steady flow and optimizing system operation. Key requirements include:

• Food-grade, non-toxic materials to maintain water purity and safety
• Corrosion-resistant construction protecting against biofouling, chemical attack, and microbial growth
• Pressure resistance to support system delivery and prevent leaks
• Long service life minimizing operation interruptions and maintenance costs
• Compliance with health standards like NSF/ANSI 61, NSF/ANSI 58
• Versatile sizing to meet residential to large commercial water storage needs

What Are Glass-Fused-to-Steel (GFS) RO Water Tanks?

Center Enamel’s GFS tanks combine robust steel substrates with an inert glass-enamel coating fused at high temperatures (820°C to 930°C), creating a seamless, extremely smooth, and chemically resistant surface ideal for storing RO purified water.

This fusion technology ensures:

• Complete protection against corrosion and microbial contamination
• An inert surface inert to chemical additives or impurities, preserving RO water quality
• Low surface roughness preventing biofilm formation and reducing cleaning needs
• Structural integrity capable of withstanding internal pressure variations and external environmental stresses
