QILEE Membrane Element Manufacturer Membrane Element Manufacturer Factory

Product Overview

- QILEE’s MBR flat membrane element is a vertical, flat-sheet membrane module built from an ABS liner, antibacterial flow-guide cloth and inlaid PVDF flat membrane. It is designed for membrane bioreactor (MBR) filtration where bottom aeration scours the membrane surface to limit sludge deposition and keep membrane performance stable over long operating periods.

Product Features

- Multi-layer PVDF structure with hydrophilic cortex, near-cortex and porous support layer forming a sponge-like topology and high porosity.

- Strong capillary action that lowers pore resistance and improves filtration flux.

- Separation layer and support layer form a semi‑interpenetrating network to enhance interlayer adhesion, blasting strength and backwash tolerance.

- Vertical orientation with bottom aeration and large-bubble scouring to facilitate cleaning.

Product Value

- Higher and more stable throughput, even at elevated activated-sludge concentrations, delivering consistent high-quality effluent.

- Increased filtration flux and improved anti-fouling reduce downtime and maintenance frequency.

- Lower total operating cost through long service life (typical 5–8 years), less frequent diaphragm replacement, and the ability to replace elements one-by-one.

Product Advantages

- Superior anti-pollution (anti-fouling) performance enabling operation under higher sludge loads.

- Good mechanical stability due to a high-strength support structure that resists tearing and guarantees water quality.

- Easier and longer cleaning cycles because of efficient bottom aeration scouring.

- Durable design with reliable backwash tolerance and extended service life, backed by QILEE’s R&D and quality-control capabilities.

Application Scenarios

- Municipal and industrial wastewater treatment using membrane bioreactors (MBRs).

- Treatment lines with high activated-sludge concentrations or difficult-to-treat influents where anti-fouling and stable flux are required.

- Upgrades or retrofits of existing MBR systems seeking lower maintenance and longer membrane life.

- Facilities prioritizing continuous, high-throughput filtration with reduced operating costs and simple element replacement.
