Introduction of BF500D Retrofit MBR Membrane
Advanced Hollow Fiber Membrane for Membrane Bioreactor Systems
The Blufox BF500D Retrofit MBR Membrane represents a significant advancement in membrane bioreactor (MBR) technology, engineered as a high-performance, drop-in replacement for the industry-standard ZeeWeed 500D membrane system. This hollow fiber membrane delivers exceptional filtration precision, operational efficiency, and extended service life for municipal and industrial wastewater treatment applications worldwide.
Manufactured with premium-grade Reinforced PVDF (polyvinylidene fluoride), the BF500D achieves superior mechanical strength, porosity, and hydrophilic properties that ensure consistent performance across diverse operating conditions.
Product Overview
Technology Foundation
The BF500D employs an outside-to-inside hollow fiber configuration that optimizes filtration efficiency while minimizing fouling potential. The membrane’s engineered pore structure (0.04 µm) provides complete biomass retention, achieving >98% TSS removal and >90% COD removal, producing effluent quality suitable for water reuse, industrial processes, and environmental discharge compliance.
Unlike conventional MBR membranes, the BF500D incorporates hydrophilized surface modification that reduces organic adhesion and extends cleaning intervals, resulting in lower operational costs and reduced maintenance frequency throughout the membrane’s service life.
