DuPont™ XUS180804 and XUS180802
Description:
The DuPont™ XUS180804 DuPont™ XUS180802 Reverse Osmosis Elements are ultra-high pressure elements offering an industry wide distinct combination of features.
• Up to 120 bar (1,740 psi), ultra-high feed pressure capability due to distinct element and membrane
Design.
• Increasing the overall efficiency of Zero-Liquid-Discharge (ZLD) by achieving very high solute
Concentrations thus helping to reduce the size of Down Stream thermal treatment
• Excellent for recovery of salts in process streams
• Robust 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.
