MBR Separate Curtain Membrane Product Characteristics

Large Flux

Design flux is 10 - 30LMH

Good Universality

Installation same as the public version of membrane shell on the market.

Strong Anti-Pollution Ability

Antimicrobial PVDF hydrophilic alloy membrane pore is uniform and fine, which makes anti-pollution ability is stronger.

Good Seal

Four - layer sealing technology membrane adopts four package to eliminate water leakage of membrane sealing shell.

Strong Anti-Pollution Ability

Socket structure design, offline cleaning more convenient

High Integral Strength

The integral strength of membrane shell is higher than the general membrane shell on the market, pressure - bearing performance is better.

Key Technology Features

Optimized Pore Structure & High Flux

0.05μm uniform pore distribution with high porosity delivers 25% higher flux than conventional membranes while maintaining excellent anti-fouling properties.

Enhanced Mechanical Strength

Tensile strength >150N and peel strength >3N withstand intensive backwashing operations, ensuring extended service life.

Advanced Anti-fouling Design

Automated hot-melt adhesive spacing creates evenly distributed fiber arrangement, effectively preventing sludge trapping and reducing cleaning frequency.

Energy-efficient Operation

QILEE pulse aeration technology reduces aeration consumption by 40% compared to continuous aeration, with air-to-water ratio below 5:1.

Flexible Operation Modes

Capable of operating with or without backwashing, enhancing water production efficiency and reducing operational costs.
