Membrane Element Suppliers System & Equipment Wholesale - QILEE

Product Overview

- AG-ULP series spiral-wound RO membrane elements from QILEE designed for low-salinity water treatment.

- Built on advanced aromatic polyamide composite technology to deliver high permeability while maintaining ≥99.5% stabilized salt rejection.

- Available in standard 8-inch vessel formats (AG-ULP-4040 and AG-ULP-8040) for easy integration into new or existing systems.

Product Features

- High flux, low-pressure design: maintains required permeate flow at roughly two-thirds the operating pressure of conventional brackish membranes.

- Key specs: max feed salinity up to 2,000 mg/L; permeate flows ~2,700 GPD (4040) and ~12,500 GPD (8040); max pressure 600 psi; operating temp up to 45 °C.

- Robust operating window: SDI ≤5, free chlorine tolerance 0.1 mg/L, continuous pH 3–10 (short-term cleaning 1–13), max element pressure drop 15 psi.

- Compatible with standard 8" pressure vessels and modular packaged systems.

Product Value

- Lower energy consumption and operating costs due to reduced required pressure.

- Fewer chemical cleans and gentler operating conditions extend membrane life and reduce maintenance expenses.

- Delivers consistent, high-quality permeate that helps meet international drinking-water standards and regulatory requirements.

- Scalable and quick to deploy in packaged or skid-mounted systems for fast time-to-service.

Product Advantages

- Proprietary membrane surface engineering and structural optimization for best-in-class permeability/rejection balance.

- Quality-focused manufacturing: safe materials, strict QC, and an experienced R&D team for continuous improvement.

- Proven market traction with repeat customers and global deployment experience through QILEE’s packaged-system expertise.

- Easy retrofitting into existing RO trains or inclusion in integrated solutions (MBR/UF/NF/RO/TMBR skids).

Application Scenarios

- Packaged and bottled drinking water production.

- Municipal and community water treatment, including residential dual-water supply systems.

- Industrial process water and park utilities, including food & beverage production.

- Groundwater and rural/urban groundwater purification, and other low-salinity desalination needs where energy efficiency and water quality are priorities.
