Benefits of Using EWPBenefits of Using EWP
• better tasting water--purification better with no TDS creep as with RO
• One technology for contaminant removal such as with As, FL, Nitrates, Perchlorate
• no membrane replacement• lower maintenance--cleaned with citric acid• 80%+ recovery• scales small or large• designs at 2,500 ppm for POU/POE
• configured into countertop appliance, water dispenser, water cooler
• 1/3 smaller size than RO• saltless water softener + more
