High Quality Membrane Element Membrane Elements Wholesale - QILEE

Product Overview

- QILEE high-quality Ultrafiltration (UF) Membrane Element (models X55 and X75) are PVDF external-pressure hollow-fiber modules designed for liquid-solid separation and fine filtration.

- Two model options: X55 (effective area 52 m², Φ225×1860 mm, wet weight 50 kg) and X75 (effective area 77 m², Φ225×2360 mm, wet weight 63 kg).

- Nominal pore size 0.03 μm, DN50 interface, suitable for modular, scalable installations.

Product Features

- Membrane material: PVDF hollow fiber; membrane form: external-pressure hollow fiber.

- Filtration modes: dead-end or crossflow. Operational flux at 25°C: 30–120 L/m²·h (dependent on feed quality).

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

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

- Feed handling: short-term inlet turbidity up to 300 NTU; produced water quality achievable to ≤0.1 NTU and SDI15 ≤3 with proper pre-treatment.

Product Value

- Delivers reliable fine-particle and microbial removal (ultrafiltration-level separation) to protect downstream processes and improve overall water quality.

- Modular design and two size options provide flexibility for retrofits, expansions, and different flow demands.

- High throughput range and robust backwash/air-scour capabilities reduce fouling impact and lower operating downtime/costs.

- Stable produced-water quality (low turbidity and SDI) supports RO pre-treatment, potable water production, and reuse applications, enabling cost savings and regulatory compliance.

Product Advantages

- Engineered and produced by QILEE with experienced designers and advanced production technology, promising consistent manufacturing quality.

- Competitive pricing and customer-first service, supported by strong technical team and after-sales support.

- Strong domestic market position and growing international presence, implying reliable supply chain and production capacity.

- Durable PVDF construction and flexible operational ranges improve longevity and applicability across varied feed conditions.

Application Scenarios

- Pre-treatment for reverse osmosis (RO) systems and desalination plants.

- Surface water and river water treatment for drinking water production.

- Industrial process water and wastewater reuse (food & beverage, pharmaceuticals, textile, electronics).

- Municipal water treatment, stormwater polishing, and aquaculture systems.

- Any application requiring stable low-turbidity, low-SDI feed water where modular ultrafiltration is appropriate (subject to proper pre-treatment for consistent performance).
