QILEE Integrated Membrane Systems and Processes Company

Product Overview

1) Product overview

Product Features

- QILEE Integrated Membrane Systems and Processes is a modular ultrafiltration membrane treatment platform built around asymmetric, graded‑porosity PVDF membranes (modified for surface charge enhancement).

Product Value

- Membrane pore size: 0.03–0.05 μm (

Product Advantages

- Scalable skid configurations cover typical flow ranges from ~5 to 130 m³/h using X‑55 (51 m²) and X‑75 (77 m²) membrane modules, with total membrane area options ~306–7,392 m². Full remote monitoring and control via integrated PLC.

Application Scenarios

2) Product features

- High selectivity membranes (graded porosity + surface charge) for SDI/TOC/turbidity control.

- Adaptive flux management that reduces energy use and adapts to seasonal/source variability.

- Chemical dosing (CEB) and CIP skids integrated: flow‑proportional dosing, diaphragm pumps, dosing 50–200 ppm, scalable cleaning tanks (2,000–5,000 L).

- Automated backwash/CEB scheduling, heating for CIP (to 40°C), and standardized maintenance cycles.

- Low chemical and energy footprint with remote automation and modular rack layouts for easy expansion.

3) Product value

- Operational cost savings: 30–60% lower chemical consumption and 25–40% lower energy use compared with conventional treatments.

- High water recovery (95–99% depending on source) increases usable output and reduces intake volumes.

- Significant footprint reduction (50–70% space savings) lowers civil and site costs.

- Predictable maintenance cycles and membrane life (4–10 years depending on source) improve budgeting and lifecycle planning.

- Customizable designs deliver fit‑for‑purpose solutions for different water qualities and regulatory needs.

4) Product advantages

- Robust technical specs: consistent pore size, PVDF durability, and surface charge for enhanced fouling resistance.

- Proven system integration: pre‑configured chemical/CIP skids and PLC control reduce installation time.

- Flexibility: multiple rack layouts and capacities let clients scale from small to large plants.

- Lower total cost of ownership via reduced chemicals, energy, and footprint.

- Backed by QILEE’s quality control, global market experience, and customer recommendations; company emphasizes R&D and customization.

5) Application scenarios

- Surface water treatment and raw water intake pretreatment (seasonal/adaptive flux control).

- Well and groundwater polishing (high flux, low fouling operation).

- RO feed polishing and SDI reduction for desalination and high‑quality industrial processes.

- Municipal tap water reinforcement and tertiary wastewater treatment / reuse where conservative flux is needed.

- Industrial process water (food & beverage, pharma, electronics), irrigation, and any scenario requiring high recovery, compact footprint, and automated operation.
