SXL-225FSFCPVC UF Module Pentair Equivalent

Product Introduction

The SXL-225FSFCPVC Ultrafiltration (UF) Module is a high-performance, industrial-grade membrane filtration product engineered to serve as a reliable equivalent to the original Pentair UF module. Constructed using durable materials and designed for seamless compatibility, the SXL-225FSFCPVC provides consistent, high-quality water filtration for a wide range of applications including industrial processing, municipal water treatment, and reverse osmosis (RO) pretreatment.

Built with polyvinyl chloride (PVC) housing and polyethersulfone (PES) hollow fiber membranes, this ultrafiltration module ensures high chemical resistance, stable performance, and excellent filtration efficiency. It supports both new installation projects and membrane replacement needs in systems originally configured with Pentair SXL series UF modules.

Working Principle

Ultrafiltration operates on the principle of membrane separation, where pressure is applied to push water through a semipermeable membrane. The SXL-225FSFCPVC UF module uses outside-in hollow fiber filtration, a robust technique ideal for high-turbidity water.

Process Overview:

1.    Feed Water Introduction
Raw or pretreated water enters the module from the exterior of the hollow fiber bundles.

2.    Selective Permeation
Water and dissolved molecules smaller than ~0.01 µm pass through the membrane wall into the lumen, while suspended solids, microorganisms, and macromolecules are rejected on the outer surface.

3.    Filtrate Collection
The clean, filtered water (permeate) is collected from inside the hollow fibers and exits via the central outlet.

4.    Periodic Cleaning
The system includes backflushing, air scouring, and chemical cleaning to restore performance and prolong membrane life.

This technique ensures high filtration rates with low energy consumption and excellent contaminant removal.
