Integrated Membrane Systems by QILEE-1

Product Overview

- Integrated MBR membrane-curtain systems by QILEE are modular, skid-mounted membrane bioreactor solutions designed for plug-and-play deployment in small to large water and wastewater projects.

- Available curtain sizes: QL-MBR-10, QL-MBR-15, QL-MBR-20 (10 / 15 / 20 m² per curtain) and skid models (e.g., QL-MBR-400 to QL-MBR-2520) to match project scale.

- Core construction: PET support with PVDF separation hollow-fiber membranes (nominal pore size 0.05 µm), external pressure hollow-fiber configuration.

Product Features

- High and stable flux: design flux 10–30 LMH; operational flux typically 15–30 L/m²·h @25°C.

- Strong anti-fouling: hydrophilic PVDF alloy, loose/hydrophilic modifications and special designs to reduce sludge accumulation and speed flux recovery.

- Robust mechanical and sealing design: four-layer sealing technology, internal reinforcement for higher integral strength, socket structure for convenient on-line cleaning and maintenance.

- Energy and process efficiency: high-porosity, uniform membrane structure and pulse aeration to reduce hydraulic resistance and operating energy (10–20% lower vs. traditional processes).

- Wide operational range: TMP 0–35 kPa, backwash up to 70 kPa, operating pH 2–10 (chemical cleaning pH 1–12), temperature 5–40°C.

Product Value

- Reliable, high-quality effluent: very low turbidity and suspended solids (typical turbidity

- Lower lifecycle costs: reduced energy consumption, extended membrane life, faster flux recovery and lower maintenance frequency/costs.

- Faster deployment and scalability: modular, skid/container-ready systems reduce installation time and on-site commissioning.

- Flexible fit for project budgets: model range supports economical choices for small, medium and large plants to optimize CAPEX/OPEX.

Product Advantages

- Best performance/price ratio emphasized by QILEE and built for high durability and manufacturability.

- Strong anti-pollution engineering (hydrophilic PVDF, loose structure, socket/on-line cleaning) that minimizes fouling and simplifies operations.

- Universal compatibility: installation dimensions match market-standard shell sizes for easier replacement/upgrade.

- High automation and process adaptability: compatible with MBR-based process flows across industries and municipal use, with pulse aeration and modular control.

- Backed by QILEE’s experience: ~20 years of process design, global deployment in 40+ countries and integrated membrane technology offerings (MBR, UF, NF/RO, TMBR, PTFE, etc.).

Application Scenarios

- Industrial wastewater: high-strength streams from dairy, food & beverage, chemical, dyeing and other industries where solids, proteins and colloids must be retained.

- Municipal wastewater: replacement or optimization of secondary clarification to simplify process trains and improve effluent consistency and automation.

- Drinking water / concentration separation: membrane separation for water purification or material concentration in specialist applications.

- Project sizing guidance: QL-MBR-10 for small stations/communities, QL-MBR-15 for medium/town-level projects, QL-MBR-20 for large municipal or industrial parks.
