FilmTech™ SW30HRLE-400 (Sea Water)
Updated on October 12, 2025
Key Features:
• Optimized combination of water production and permeate quality.
• Excellent durability resulting in stable, long-term performance.
• Longer storage time and warranty cover age with improved sustainability footprint versus our wet RO
Membrane elements.
Key Application:
• Sea Water desalination for municipal and industrial applications.
• Suitable for medium and high feed water salinity.
• Offers balance between permeate quality and energy consumption.
• Applicable for optimized Internally Stage Designs (ISD) in combination with other FilmTechTM sea
water membranes.
