The Arium® Advance EDI Type 2 and Arium® Advance RO Type 3 water purification systems are used to obtain high ion retention rates while maintaining optimal water yield. They reliably remove oxidants, heavy metal ions, and particles from tap water, helping ensure consistent feedwater quality. The built-in iJust function further optimizes purified water quality while supporting efficient water usage.
Following purification, the pretreated water is stored in the closed Arium® Bagtank system. Here, the stored water is protected from secondary contamination, helping to maintain its quality.
