QILEE Membrane Element Manufacturers Manufacturer

Product Overview

QILEE AG‑XLFR series reverse‑osmosis membrane elements are industrial RO modules designed for high‑performance desalination and wastewater treatment. Available in two standard sizes (AG‑4040XLFR and AG‑8040XLFR), they feature large active areas (85 ft2 / 400 ft2) and high permeate capacities (≈2,000 GPD and ≈11,500 GPD respectively). The elements are built to industrial operating limits (max 600 psi, service temperature up to 45 °C) and are produced under a strict quality management system.

Product Features

- Advanced membrane surface: improved hydrophilicity, optimized charge characteristics and smoother surface to inhibit pollutant and microorganism adhesion.

- 34‑mil wide feed‑channel spacer to reduce fouling potential and lower system pressure drop.

- High stabilized salt rejection: AG‑8040XLFR ~99.75% (min 99.65%); AG‑4040XLFR ~99.6% (min 99.5%).

- Robust operating tolerances: pH (continuous 3–10, short‑term 1–10), low free‑chlorine tolerance (0.1 mg/L), max element pressure drop 15 psi.

- Good cleanability and effective performance recovery after cleaning; stable operation in high‑fouling applications.

Product Value

- Delivers high water quality with market‑leading salt rejection, supporting regulatory and process requirements.

- Longer service life and reduced fouling lead to lower downtime and maintenance costs.

- Lower pressure drop and improved cleanability reduce energy consumption and chemical cleaning frequency, lowering total cost of ownership.

- Scalable options (4040 and 8040) fit a range of plant sizes and flow needs.

Product Advantages

- Technical innovation in membrane surface chemistry and channel geometry that minimizes biofouling and scaling.

- High mechanical and chemical resilience enabling use across varied industrial conditions.

- Proven recovery performance after cleaning improves reliability in challenging feedwaters.

- Manufactured with strict quality control and supported by a company with structured R&D, sales channels and service capabilities.

Application Scenarios

- Wastewater reclamation and reuse (municipal and industrial).

- RO concentrate treatment and industrial wastewater recycling.

- Municipal sewage treatment and tertiary filtration stages.

- Heavy industry: power generation, metallurgy, steel, chemical processing, and textile manufacturing where high rejection and fouling resistance are required.
