High-precision UF for RO protection

Product Overview

Ultrafiltration (UF) equipment is a core membrane-based separation system widely 

used for industrial raw water purification, circulating water filtration, and wastewater reuse. 

As a low-pressure physical filtration technology, UF systems effectively remove colloids, 

suspended particles, bacteria, macromolecular organics, and turbidity without 

the need for chemical dosing. Compared with conventional sand filters and activated 

carbon filters, modern UF equipment delivers superior filtration accuracy, 

consistent effluent quality, and fully automated operation. 

It serves both as an ideal pretreatment for reverse osmosis (RO) systems and as a standalone 

purification unit across diverse industrial sectors. We supply complete UF systems along with

 compatible membrane elements, ensuring long-term stable performance and significantly 

reducing overall maintenance costs.

Working Principle

Industrial UF equipment operates on the principle of physical membrane separation. 

Under low operating pressure, feedwater flows through the inner surface of hollow-fiber

 membranes. Water molecules and dissolved minerals pass freely through the membrane pores,

 while suspended solids, colloids, bacteria, and larger impurities are retained on the 

membrane surface. The system employs cross-flow filtration to minimize surface fouling. 

Combined with automatic backwashing and clean-in-place (CIP) functions, 

the equipment periodically flushes away trapped contaminants, maintaining stable

 membrane flux and continuous production efficiency. The entire purification process is

 purely physical—free of chemical additives—ensuring consistent, high-quality permeate 

over extended operating cycles.

Core Product Advantages

This industrial UF system offers distinct technical and operational benefits that overcome 

common shortcomings of traditional filtration methods:

· Ultra-High Filtration Precision – Effectively removes fine bacteria, colloids, 

and macromolecular impurities responsible for turbidity and water quality instability, 

delivering purified water that meets rigorous industrial production standards.

· Fully Automated Operation – Integrated PLC-based control supports one-touch start-up, 

automatic production, scheduled backwashing, and chemical cleaning, drastically reducing 

manual intervention and operational errors.

· Energy-Efficient Low-Pressure Design – Stable low-pressure operation minimizes energy

 consumption, helping enterprises reduce long-term water treatment costs.

· Modular & Scalable Construction – The skid-mounted modular design enables flexible 

capacity expansion as project water demand grows, eliminating equipment redundancy and 

secondary capital investment.

· High-Antifouling PVDF Membrane – The advanced PVDF membrane material resists organic

 fouling and microbial adhesion. Combined with an integrated flushing system, 

it effectively retards membrane fouling, extends membrane service life, reduces replacement 

frequency, and lowers downstream maintenance costs.

· Versatile Feedwater Compatibility – Handles a wide range of water sources, 

including river water, well water, tap water, and pre-treated industrial wastewater, 

with strong tolerance to varying water quality conditions—ensuring 24/7 stable production.
