Ultrafiltration (UF) Membrane Filter System

Description

Ultrafiltration (UF) Membrane Filter System

An ultrafiltration (UF) membrane filter is a pressure-driven filtration system that removes bacteria, suspended solids, and colloids from water using microporous membranes at a filtration range between 0.01 and 0.1 microns. It is a standard method for industrial water treatment, wastewater recycling, and reverse osmosis (RO) pre-treatment. These UF water filters save energy, reduce chemical use, and provide reliable ultrafiltration water treatment. 

How Our Ultrafiltration (UF) Membrane Filter System Works

The working principle of UF is simple, but the engineering behind it matters a lot when you’re selecting a supplier for a large project. 

Step 1: Feed Water Entry

Raw feed water or pre-screened feed water flows into the UF module under low operating pressure, which is usually between 0.04 and 0.3 MPa. One of the top benefits of UF over RO systems is the low-pressure requirement; this directly decreases energy use and operational expenses throughout the project lifecycle at no cost to the quality of filtration output.

 

Step 2: Outside-In Hollow Fiber Filtration

Oxymo Technology UF modules have an outside-in flow setup. The hollow fiber is enclosed by feed water on the outside, and clean filtered water, known as permeate, is collected on the inside. This design can cope with high-turbidity feed water, and it remains stable even when there are changes in the inlet water quality because of the seasonal or industrial changes.

 

Step 3: Physical Membrane Barrier

The PVDF hollow fiber membrane is used as a specific physical barrier. It has a pore size of 0.03-0.05 μm, which captures particles, bacteria, viruses, and colloids on the surface of the membrane or inside the fiber wall. Water molecules and dissolved minerals smaller than the pores keep on moving forward, thus leaving the permeate turbidity at a constant low of less than 0.2 NTU.

 

Step 4 Dead-End or Cross-Flow Operation

The system operates in two modes depending on the quality of your feed water and the use. Dead-end mode directs the entire feed water across the membrane and is applicable to low-turbidity water and high-recovery goals. Cross-flow mode transfers water across the surface of the membrane and produces less fouling accumulation – so it is the most popular when used in industrial effluent and wastewater reuse.

 

Step 5: Backwash and Chemical Cleaning (CIP/CEB)

With time, the surface of the membrane gets covered by retained solids. This is controlled by the system by regular backwashing, chemically enhanced backwash (CEB), and full clean-in-place (CIP). Oxymo Technology membranes can withstand up to 5000 ppm concentration of NaClO and work under pH 1-13 without harming the membrane structure and reducing its working time.

Key Benefits of UF Membrane Filters for Industrial & Municipal Projects

As a leading ultrafiltration membrane manufacturer, Oxymo Technology delivers high-performance UF solutions to B2B buyers.

Low-pressure, energy-efficient design

UF systems have a TMP of 0.04-0.3 MPa – much less than RO or NF technologies. This low pressure need saves directly on the power consumption throughout the project’s life. In large plants with 24/7 operations, such energy savings accumulate to a significant saving on overall operational costs without affecting filtration performance or output quality.

 

Consistent High-Quality Filtration Output

Oxymo Technology UF membranes with a pore size of 0.03-0.05 μ and MWCO of 130K-150K remove bacteria, viruses, turbidity, and colloids effectively. Under normal conditions, turbidity of permeate remains at less than 0.2 NTU – a critical parameter in drinking water projects, RO pretreatment systems, or any other systems where stability of the downstream processes requires uniform quality of inlet water.

 

Chemically Resistant PVDF Hollow Fiber Construction

Oxymo Technology membranes are constructed with foam-structure PVDF hollow fiber material. PVDF is resistant to chlorine, acids, and alkalis – the most common and widely used chemicals in cleaning industrial membranes. This chemical stability is a direct extension of the life of the membrane, decreases replacement rates, and reduces the long-term maintenance costs in aggressive or variable-quality feedwater conditions.

 

Wide pH & Temperature Operating Range

The membranes work in pH 1-13 and temperatures ranging between 5°C and 50°C. The wide operating range of these makes them applicable to municipal water treatment as well as a challenging industrial application where feed water chemistry may differ greatly. You do not need to pre-treat too hard – the membrane can accept a broad spectrum of inlet conditions with both performance stability and a slow fouling rate.

 

OEM-Friendly Modular Sizing

The modules have diameters between 90 and 250 mm and membrane areas of 8 to 75 m²/module. This flexibility makes it easy to integrate into skid-mounted, containerized, or turnkey system configurations. The benefits of OEM manufacturers and EPC contractors include less engineering complexity, quicker system assembly, and less scaling when the project flow rate requirements grow over time.

 

Reduced Chemical Pre-Treatment Dependency

Physical membrane filtration saves you the use of coagulants, flocculants and other pre-treatment chemicals, which are not only expensive but increase operational complexity. Fewer chemicals mean simpler dosing systems, lower consumable costs, and reduced chemical waste handling – making your overall water treatment system leaner, cleaner, and easier to operate and maintain at both small and large project scales.

Application Areas of UF Membrane for Global B2B Projects

Drinking Water & Municipal Treatment

Oxymo Technology UF modules support surface and groundwater and municipal treatment facilities through their ability to remove pathogens and turbidity from both large treatment plants and decentralized systems and containerized units.

Industrial & Wastewater Reuse

UF modules operate as ideal equipment for tertiary treatment, effluent polishing, and process reuse because they remove suspended solids and biomass to provide stable feed water for reuse and downstream RO and NF systems.

Food, Beverage, Pharma & High-Purity Water

OEMs use UF to produce high-purity water and ingredients because it provides microbial control while removing particles and maintaining mineral composition and product integrity.

Desalination & RO Pretreatment

UF serves as RO pretreatment because it reduces SDI and turbidity and fouling, which results in longer membrane life and decreased chemical requirements and better performance for seawater and brackish water systems.

UF vs. MF vs. RO vs. NF: Which Membrane Technology Is Right for Your Project?

Choosing the right membrane technology for your project means understanding where each sits in the filtration spectrum.

 

Parameter	Conventional Filtration	Ultrafiltration (UF)	Nanofiltration (NF)	Reverse Osmosis (RO)
Pore Size	>1 µm	0.01–0.1 µm	0.001–0.01 µm	<0.001 µm
Removes	Suspended solids	Bacteria, colloids, viruses	Divalent ions, organics	Dissolved salts, ions
Operating Pressure	Very low	Low (0.04–0.3 MPa)	Medium	High
Energy Consumption	Low	Low	Medium	High
Chemical Use	High	Low	Medium	Medium-High
Best For	Pre-filtration	Pre-RO, reuse, drinking water	Softening, organics removal	Desalination, pure water

 

The takeaway for B2B buyers: UF is an important bridging solution – It is much more effective at removing contaminants than traditional filtration but requires a fraction of the energy and pressure required by RO. In the stack, it is the least expensive solution in most pretreatment and water reuse applications.
