Reliable Membrane Element Manufacturers Company

Product Overview

1) Product overview

Product Features

- QILEE ultrafiltration membrane elements (models X55 and X75) are PVDF external-pressure hollow-fiber modules designed for reliable micro/ultrafiltration.

Product Value

- Nominal pore size: 0.03 μm; effective membrane area: X55 = 52 m², X75 = 77 m².

Product Advantages

- Standard interfaces (DN50), compact cylindrical dimensions, and wet weights of 50 kg (X55) and 63 kg (X75).

Application Scenarios

- Suitable for dead-end or crossflow filtration; designed for stable daily operation with proper pre-treatment.

2) Product features

- Membrane material: PVDF hollow-fiber for chemical and mechanical robustness.

- Fine retention: 0.03 μm nominal pore size delivers very low turbidity and particulate removal.

- Operational ranges: pH 2–10, temperature 5–40°C, max inlet pressure ≤0.6 MPa, max TMP ≤0.2 MPa.

- Flux capability: 30–120 L/m²·h at 25°C (dependent on feed water quality).

- Cleaning/backwash support: backwash flow 80–120 L/m²·h, backwash pressure ≤0.25 MPa, air scour 4–12 Nm³/h per unit (air inlet ≤0.1–0.25 MPa).

3) Product value

- Consistently high produced-water quality when paired with appropriate pre-treatment (typical output turbidity ≤0.1 NTU, SDI15 ≤3.0).

- Reduces downstream treatment load (e.g., protects RO systems), supporting water reuse and process water quality control.

- Offers long service life and reliable performance, lowering lifecycle operating costs and maintenance frequency.

- Standardized design and stable supply from an experienced manufacturer simplify system integration and procurement.

4) Product advantages

- High reliability and refined build quality achieved through standardized production and quality control.

- Dedicated R&D and production expertise at QILEE provides technical support and customized guidance.

- Flexible operation modes (dead-end or crossflow) and robust operating windows accommodate varied feed waters (short-term inlet turbidity up to 300 NTU).

- Easy to clean and maintain (backwash/air-scour capable), with industry-standard mechanical interfaces for retrofit or new systems.

5) Application scenarios

- Pretreatment for reverse osmosis and other membrane systems to protect downstream units.

- Municipal and industrial surface water and groundwater ultrafiltration for potable or process water production.

- Wastewater reclamation and reuse for industrial process water, irrigation, or non-potable applications.

- Food & beverage, pharmaceutical, and aquaculture systems requiring fine particulate and microbial removal.

- High-turbidity feed clarification, stormwater treatment, and other applications where stable low-turbidity permeate is required.
