RO XLERO XLE

Summary

Product Identification

The MICRODYN RO XLE series consists of ultra-low energy reverse osmosis (RO) membrane elements designed for water purification applications where reduced energy consumption is critical. These elements feature low-energy membranes to upgrade existing RO systems and operate under ultra-low pressure conditions.

• Membrane Chemistry: Thin-Film Composite Polyamide
• Construction: Spiral-Wound Membrane Element with Fiberglass Outerwrap (or Tape outerwrap for some models)

Performance Specifications

The MICRODYN RO XLE elements offer high salt rejection rates and consistent permeate flow.

• Stabilized Salt Rejection: 99.2%
• Minimum Salt Rejection: 99.0%

Performance data is based on test conditions of 500 ppm NaCl, 6.9 bar (100 psi), 25°C (77°F), 15% recovery, pH 8.0, and 30 minutes operation. Actual flow rates will be no more than 15% below the values shown.

Important Information

• Start-up: MANN+HUMMEL Water & Fluid Solutions recommends flushing elements for 30 minutes at low pressure and discarding permeate during the flush. Consult the Element Start-Up Guide – System Start-Up (TSG-O-005) for detailed procedures.
• Cleaning: MICRODYN RO membrane elements require periodic cleaning. Refer to the Membrane Cleaning Guide – Water Application Elements (TSG-C-001) for instructions.
• Storage: Proper storage of MICRODYN RO membrane elements is essential. See Element Storage Guides (TSG-O-009 & TSG-O-010).
