Summary
Product identification
DOW™ Specialty Membrane XUS180804 and XUS180802 Reverse Osmosis Elements are ultra-high pressure, high-rejection elements designed for industrial water purification.
Key features:
- Up to 120 bar (1,740 psi), ultra-high feed pressure capability due to distinct element and membrane design.
- Increases overall efficiency of Zero-Liquid-Discharge (ZLD) by achieving very high solute concentrations, helping to reduce the size of downstream thermal treatment.
- Excellent for recovery of salts in process streams.
- Robust DOW FILMTEC™ reverse osmosis (RO) membrane sheet.
- 34 mil feed spacer to lessen the impact of fouling on the pressure drop across a vessel and to enhance cleaning effectiveness.
