Advanced Membrane Element Suppliers Company

Product Overview

1) Product overview

Product Features

The AG-ULP series from QILEE is an advanced aromatic polyamide composite reverse-osmosis membrane element family designed for low‑salinity water treatment. It is available across standard sizes (including AG-ULP-8040 and AG-ULP-4040) and fits common 8‑inch pressure vessel systems. Typical stabilized salt rejection is ≥99.5%.

Product Advantages

- Precision-engineered membrane surface and optimized structure for high permeability.

Application Scenarios

- Low operating pressure requirement (about two‑thirds of conventional brackish membranes) while maintaining 99.5% salt rejection.

- Model highlights: AG-ULP-8040 (≈40.9 m² active area, ~12,500 GPD/47.3 m³/d), AG-ULP-4040 (≈9.3 m², ~2,700 GPD/10.2 m³/d).

- Operating limits: max pressure up to 600 psi (4.14 MPa), max feed salinity 2,000 mg/L, SDI ≤5, continuous pH 3–10 (short-term 1–13), free chlorine tolerance 0.1 mg/L.

3) Product value

- Lower energy consumption and reduced OPEX due to high permeability at reduced pressure.

- Consistent, high-quality permeate that meets international drinking water standards.

- Reduced chemical use and gentler operating conditions extend membrane life and lower maintenance costs.

- Scalable and compatible design simplifies retrofits and new installations, accelerating time to value.

4) Product advantages

- Superior permeability/rejection balance: high flux with ≥99.5% salt rejection.

- Energy-efficient operation (operating pressure ~2/3 that of traditional brackish membranes).

- Wide model range and reliable manufacturing controls from an experienced supplier (QILEE), supporting global distribution.

- Robust operational envelope (high max pressure, wide pH cleaning range) and low pressure-drop design for consistent system performance.

5) Application scenarios

- Packaged and bottled drinking water production.

- Municipal and community water treatment (water treatment plants, groundwater purification).

- Residential and commercial dual‑water supply systems.

- Industrial process water and industrial park water treatment.

- Food & beverage manufacturing process water and other low‑salinity desalination needs.
