Product Description
The 4 m³/h Industrial Ultrafiltration (UF) Water Treatment System is designed for the removal of suspended solids, colloids, fine particles, bacteria and high-molecular-weight organic matter from water.
Using hollow-fiber ultrafiltration membrane technology, the system provides stable and consistent filtered water for industrial water purification, drinking-water pretreatment, RO system pretreatment and selected water reuse applications.
With a compact skid-mounted design, automatic backwashing and optional PLC control, the system is suitable for continuous industrial operation while helping reduce membrane fouling and routine maintenance requirements.

*Actual capacity, recovery and membrane flux depend on raw-water quality, temperature, operating conditions and system design.
2. What Does the UF System Remove?
Ultrafiltration uses a physical membrane separation process to remove particulate and microbiological contaminants while allowing water and dissolved ions to pass through the membrane.
The system is mainly designed to reduce:
- • Suspended solids
- • Turbidity
- • Colloidal particles
- • Fine particles
- • Bacteria and microorganisms
- • High-molecular-weight organic matter
Under suitable feed-water and operating conditions, UF permeate can typically achieve low turbidity and low SDI, making ultrafiltration particularly suitable as pretreatment for reverse osmosis systems.
Important: UF Does Not Remove Dissolved Salts
Ultrafiltration is not a desalination process.
Dissolved salts, conductivity, hardness ions and other dissolved substances generally pass through UF membranes. If the project requires lower TDS or conductivity, a downstream Reverse Osmosis (RO) System should be used.
3. Suitable Raw Water Sources
The 4 m³/h UF system can be customized for different feed-water conditions, including:
- • Municipal tap water
- • Borehole and well water
- • River and lake water
- • Reservoir water
- • Process water
- • Cooling circulating water
- • Pretreated industrial wastewater
- • RO pretreatment feed water
For surface water, wastewater or other raw water with high turbidity, suspended solids or organic loading, additional pretreatment may be required before the UF membranes.
The final process configuration should therefore be determined according to the raw-water analysis report and target product-water requirements.
4. Typical Treatment Process
Main Process：Raw Water → Booster Pump → Pre-treatment Unit → Cartridge Security Filter → UF Membrane System → Permeate Water Tank → Reuse
24-hour fully automatic continuous operation, effectively reduce membrane fouling and extend system service life.
UF as RO Pretreatment
Raw Water → Pretreatment → UF System → Cartridge Filter → RO System → Product Water Tank
UF can provide stable pretreatment for downstream RO membranes by reducing turbidity, suspended solids and colloidal contamination.
The actual process will be designed according to raw-water quality rather than using one fixed configuration for every project.
5. Main System Components
A typical 4 m³/h industrial UF system can include:
- • UF membrane modules
- • UF membrane housing / rack
- • Feed water pump
- • Backwash pump
- • Automatic valves
- • Flow meters
- • Pressure gauges / transmitters
- • Control panel
- • PLC and HMI touch screen
- • Chemical cleaning connections
- • Skid frame
- • Interconnecting pipelines
Pretreatment equipment, tanks, dosing systems and disinfection systems can be supplied according to project requirements.

9. Why Choose a Customized UF System?
UF membrane performance is closely related to feed-water quality.
Using the same membrane flux and cleaning strategy for every project may result in excessive fouling, unstable output or unnecessarily high operating costs.
For this reason, the UF system should be selected and designed according to factors such as:
- • Raw-water turbidity
- • Suspended solids
- • COD / organic loading
- • Water temperature
- • Required permeate capacity
- • Daily operating hours
- • Target water quality
- • Downstream treatment process
Based on these parameters, the membrane quantity, design flux, backwash frequency and pretreatment process can be selected for the specific project.
10. Frequently Asked Questions
Q: Can UF reduce TDS or conductivity?
No. Ultrafiltration mainly removes suspended, colloidal and microbiological contaminants. Dissolved salts require technologies such as reverse osmosis.
Q: Does 4 m³/h mean feed-water capacity or product-water capacity?
The 4 m³/h rating refers to the designed UF permeate capacity. Required feed-water flow is higher because water is also consumed during backwashing and cleaning.
Q: Can the system operate continuously?
Yes. The system can be designed for continuous industrial operation with automatic filtration and backwash cycles. The final operating program depends on the membrane design and feed-water conditions.
Q: Can river water be fed directly into the UF membranes?
This depends on the raw-water quality. High-turbidity surface water normally requires coagulation, sedimentation or other pretreatment before UF.
Q: How often does the UF membrane need cleaning?
Backwashing is performed automatically according to the operating program. Chemical-enhanced backwash or CIP frequency depends on membrane fouling and feed-water quality.
Q: Can UF be installed before an RO system?
Yes. UF is widely used as RO pretreatment because it can reduce suspended solids, colloids and turbidity before water enters the RO membranes.
Q: Can you customize the system according to our project?
Yes. Capacity, membrane configuration, pretreatment, materials, automation, electrical standards and post-treatment can be customized according to project requirements.
