PUREONE 4040/8040 MEMBRANE
Industrial
The Pureone 2540 membrane is a high-performance reverse osmosis (RO) module designed as a replacement part for water purification systems.
Standard Modules
Energy‑Saving XLE/ELE
High‑Flow / High‑Pressure Variants
Excellent Water Quality
Operational Efficiency
Description
The Pureone 2540 membrane is a top-tier RO replacement module, offering:
Plug-and-play compatibility with common systems.
Robust removal of dissolved solids (99%+).
Efficiency through low-pressure operation (XLE-type models).
Reliability over a wide service range.
Ideal for both retrofit projects and system upgrades. Make sure your prefilters are in good shape (particularly for chlorine removal), and your pump matches the operating pressure for best results.
Features
Membrane Type: Thin-film composite (TFC), spiral-wound design—ideal for efficient contaminant rejection.
Dimensions: 2.5″ × 40″ (≈ 6.35 cm × 101.6 cm), fitting standard housings.
Pressure Rating: Typically operates around 100–225 psi; exact specs depend on whether the variant is energy-efficient or standard.
Salt Rejection: Around 99–99.5%, ensuring high-quality drinking water.
Flow Rate: Commonly ranges from 700 to 1,000+ gallons per day (GPD), depending on product grade (standard vs. XLE/ELE)
Operating pH: Usually from 2‑11 (continuous) and can withstand up to pH 12 for clean-in-place (CIP) processes
Temperature Tolerance: Typically up to 45°C (113 °F) under standard operating pressures .
Chlorine Tolerance: Essentially zero, so feed water should have been through pre-carbon filtration.
