Anti-Fouling PVDF MBR Membrane Module with High Flux and 0.1 μm Filtration Precision

📋Product Description

Fouling is the No.1 challenge in membrane bioreactor operation — and this anti-fouling PVDF MBR membrane module is engineered specifically to solve it. Featuring advanced amphiphilic copolymer blending technology, the membrane achieves permanent hydrophilicity during the preparation stage, unlike conventional membranes that rely on surface coatings which wash out over time. This intrinsic modification endows the PVDF material with lasting resistance to acid, alkali, and oxidation while maintaining high water permeability throughout its service life.

The modified membrane delivers an exceptional 80%–90% flux recovery rate after drying, effectively preventing pore collapse and eliminating two chronic drawbacks of conventional products: the leaching of hydrophilic additives and the adsorption of hydrophobic pollutants. This means lower trans-membrane pressure, less frequent chemical cleaning, reduced energy consumption, and a significantly longer replacement cycle — directly translating into lower lifecycle costs for plant operators.

The module adopts a new uniform filament arrangement structure with filament spacing precisely controlled at 0.8 mm (±0.1 mm), maximizing effective filtration area within a compact footprint. Quick-plug connectors enable tool-free disassembly, and the integrated aeration design scours the fiber surface continuously, keeping the membrane clean during normal operation.
