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
