Product Overview
The BF100N Premium Series is Blufox’s highest-grade hollow fiber MBR membrane, built for both municipal and industrial wastewater treatment applications. Designed with precision-engineered PVDF hollow fibers, the BF100N delivers stable filtration performance even under variable load conditions — making it the preferred choice for plant operators who cannot afford downtime or inconsistent output.
Backed by 15+ years of water treatment expertise through Albion Ecotech, every BF100N unit is manufactured under ISO 9001 certified quality standards and undergoes a rigorous post-production quality audit before dispatch.
Design Philosophy
Built for Long-Term Plant Performance
The BF100N is not just a membrane – it is a long-term investment in your plant’s output reliability. Its premium fiber construction ensures stable flux rates and consistent permeate quality across the membrane’s full service life.
Wide Flux Range for Variable Loads
Designed to operate across a flux range of 10–40 LMH, the BF 100N handles variable influent loads without performance degradation – ideal for plants that experience seasonal or process-driven fluctuation in wastewater volume.
ISO 9001 Certified Manufacturing
Every BF100N unit is produced under a certified quality management system. Post-production inspection is standard – not optional. You receive a membrane that has been verified before it leaves our facility.
Retrofit-Ready Design
The BF100N is engineered for straightforward installation into existing MBR systems. Whether you are replacing a worn-out module or upgrading from a lower-grade membrane, the BF 100N integrates without requiring civil modifications or extended shutdown periods.
With a fiber diameter of 2.0–2.5 mm and a precision-controlled pore size of 0.03–0.2 micron, the BF100N delivers reliable solids rejection and effluent clarity – meeting discharge norms consistently without over-engineering your operation.

BLUFOX BF500S: A Structured 500S Replacement Process
We don’t select a replacement membrane based solely on datasheet values. Every 500S replacement project starts with a comprehensive evaluation of the existing 500SA cassette and its actual operating conditions. By understanding how your system performs in practice, we can recommend the most suitable membrane solution for maximum efficiency and seamless integration.
01. Project Assessment
We begin by evaluating the overall project requirements, including treatment capacity, existing 500SA cassette arrangement, and the total quantity of replacement membranes required.
02. Existing Cassette Evaluation
Our team assesses the condition of the installed 500SA cassette, including frame structure and associated components, to confirm its suitability for membrane replacement.
03. Membrane Selection & Confirmation
Based on the project specifications, we determine the most suitable 500S membrane model, verify technical requirements, and define the complete supply scope.
04. System Compatibility Review
We analyze the current treatment process and operating conditions—including aeration, pumping, and system hydraulics—to ensure seamless integration and reliable long-term performance.
05. Replacement & Installation Support
Comprehensive installation guidance is provided to simplify the replacement process, reduce downtime, and ensure efficient commissioning.
06. Performance Verification & Follow-Up
Following installation, we conduct a performance review to confirm stable operation, membrane efficiency, and consistent effluent quality, ensuring the system delivers the expected results.
Send us your current 500S Cassette details – we will confirm compatibility.
