HFU-1020AN UF Module Toray Equivalent

Product Introduction

The HFU-1020AN Ultrafiltration (UF) Module is an industrial-grade membrane designed as a direct equivalent to the Toray HFU-1020AN module. Built for demanding municipal and industrial applications, this module offers precise water quality control, long-term reliability, and seamless system integration.

Constructed with top-tier hollow fiber membranes and housed in durable materials, the HFU-1020AN delivers excellent removal of suspended solids, bacteria, colloids, and high-molecular-weight organics. It supports critical functions such as potable water production, wastewater reuse, reverse osmosis (RO) pretreatment, and process water polishing—ensuring efficiency, cost-effectiveness, and sustainability.

Working Principle

The HFU-1020AN employs a proven outside-in ultrafiltration mechanism using hollow fiber membranes:

1.    Feed Water Introduction
Raw or pretreated water enters the exterior of the fiber bundle inside the module.

2.    Selective Filtration
Pressure pushes water through the membrane pore walls (nominal pore size ~0.03 µm), blocking suspended solids, bacteria, viruses, and colloids.

3.    Permeate Collection
The filtered water flows through each fiber’s interior and is collected via the permeate manifold.

4.    Cleaning Protocol
The system performs automated backwash and air scouring to dislodge retained contaminants. Periodic chemical cleaning-in-place (CIP) restores membrane performance.

This ensures continuous operation with consistent water quality, high recovery (>90%), and energy-efficient results, while preserving membrane integrity.
