SXL-225 FSFC UF Membrane Norit Equivalent

Product Introduction

The SXL‑225 Flow‑Spun Hollow Fiber (FSFC) Ultrafiltration (UF) Membrane is a premium industrial-grade filtration module designed as a fully compatible equivalent to the Norit SXL‑225 system. Engineered for use in municipal and industrial water treatment applications, this module delivers high-performance filtration, excellent durability, and low operational costs.

The SXL‑225 uses flow‑spun hollow fiber membranes, manufactured under precise conditions to ensure consistent pore structure and mechanical robustness. It’s ideal for tasks like drinking water purification, wastewater reuse, reverse osmosis (RO) pretreatment, and industrial process water recovery.

Working Principle

Operating under the outside‑in filtration mechanism, the SXL‑225 module allows water to flow across the exterior surface of the hollow fibers, capturing particles and microorganisms while clean water passes inward.

Filtration Process:

1.    Feedwater Entry: Untreated water enters the shell side of the module.

2.    Filtration Stage: The water permeates through 0.03 µm pores, removing suspended solids, bacteria, viruses, and colloids.

3.    Permeate Collection: Filtered water collects in the fiber lumen and exits via dedicated permeate outlets.

4.    Cleaning Cycle: Routine backwash, air scour, and periodic chemical cleaning-in-place (CIP) restore membrane performance.

This design supports continuous operation, high recovery rates (> 95%), and low energy consumption.
