QILEE High Quality Membrane Element High Quality Membrane Element Manufacturer

Product Overview

QILEE’s AG-SWRO series high-quality membrane elements are next-generation aromatic polyamide composite membranes engineered for seawater reverse osmosis and high-salinity applications. Available in standard sizes (e.g., AG-SW8040HR and AG-SW4040HR), they deliver industrial-scale permeate flows (up to ~7,500 GPD per element) and are built for demanding feedwater conditions from brackish to full-strength seawater.

Product Features

- Very high salt rejection (>99.7% typical, ≥99.5% minimum).

- High stabilized permeate flow (models up to ~7,500 GPD / 28.4 m3/d).

- Robust mechanical limits: maximum operating pressure up to 1,200 psi (8.3 MPa); operating temperature 0–45 °C.

- Feed tolerance: handles TDS from 10,000 mg/L to full-strength seawater, maximum SDI15 = 5, free chlorine tolerance 0.1 mg/L.

- Wide pH cleaning/operation windows (continuous pH 3–10; short-term cleaning 1–13) and low pressure drop per element.

Product Value

These membranes provide reliable, high-efficiency desalination that lowers unit water cost by increasing water production and reducing chemical and energy consumption. Their stability under high pressure and variable salinity/temperature reduces downtime and replacement frequency, improving overall system availability and lifetime cost-effectiveness for municipal, industrial, and offshore projects.

Product Advantages

- Enhanced fouling resistance and optimized surface properties for sustained high flux.

- Strong structural design for long-term stability under fluctuating feed conditions and extreme pressures.

- Compatibility with existing seawater RO system configurations and scalable element sizes.

- Manufactured on efficient production lines for consistent quality, long service life, and competitive pricing backed by QILEE’s production, sales and service capabilities.

Application Scenarios

Ideal for municipal seawater desalination plants, industrial water treatment, power plant cooling water, offshore platforms and marine vessels, coastal resorts and hotels, and mining/metallurgical water systems—especially where high salinity, variable temperature, and demanding operational reliability are required.
