HDNUF-6000L Fully Automatic Hollow Fiber Ultrafiltration System

Product Introduction
The HDNUF-6000L Fully Automatic Hollow Fiber Ultrafiltration System is designed for the separation, concentration, and purification of macromolecules, as well as water treatment applications. Hollow fiber ultrafiltration membranes operate at relatively low pressure and normal temperatures, enabling membrane separation without phase changes.
The system uses PLC-controlled automatic backwashing and automatic forward and reverse flushing to support stable filtration performance. Its stainless steel construction, sanitary SUS304 pneumatic butterfly valves, and integrated human-machine interface (HMI) make it suitable for industrial water treatment and process applications.
Depending on the membrane configuration, hollow fiber ultrafiltration can remove colloidal particles, bacteria, suspended impurities, and high-molecular-weight substances while retaining selected dissolved minerals. It can also serve as pretreatment for reverse osmosis (RO) systems or as a polishing step in high-purity water production.

Performance Features
• PLC-Controlled Automatic Backwashing: Automatic backwashing helps maintain membrane performance and reduce manual intervention.
• Duty/Standby Configuration: The system adopts a one-in-service, one-standby arrangement to support operational continuity.
• Automatic Forward and Reverse Flushing: Supports membrane cleaning and helps control fouling during operation.
• Manual Chemical Cleaning: Enables chemical cleaning when required by membrane fouling conditions and operating procedures.
• Stainless Steel Construction: Stainless steel equipment construction supports durability in industrial environments.
• Sanitary Pneumatic Valves: Uses SUS304 sanitary pneumatic butterfly valves for automated flow control.
• Multiple Pump Protections: Water pumps include dry-run or low-water protection, overload protection, overtemperature protection, and overcurrent protection.
• Integrated HMI and PLC Control: The operator interface displays relevant operating information and supports PLC-based remote control.
• Flexible Application: Suitable for water filtration, process-water treatment, macromolecule concentration, and RO pretreatment, subject to membrane selection and feed-water conditions.

Working Principle
Hollow fiber ultrafiltration uses semipermeable membranes with selective pore structures to separate suspended and macromolecular substances from water or process liquids.
During filtration, feed liquid passes along or through the hollow fiber membrane structure under a controlled pressure difference. Water and sufficiently small dissolved components pass through the membrane as permeate, while larger particles and retained macromolecules remain in the concentrated stream.
The PLC control system manages automatic backwashing and forward/reverse flushing according to the configured operating sequence. When membrane fouling requires additional treatment, manual chemical cleaning can be performed using membrane-compatible cleaning procedures. The duty/standby configuration and pump protection functions support safer and more reliable operation.

Frequently Asked Questions
Q1: What is the HDNUF-6000L ultrafiltration system used for?
It is designed for membrane filtration, water purification, macromolecule separation, concentration, and pretreatment for reverse osmosis systems.
Q2: What are the main advantages of hollow fiber ultrafiltration?
Hollow fiber membranes provide a large membrane area in a compact structure and can separate colloids and macromolecular substances under relatively low-pressure conditions.
Q3: Does the HDNUF-6000L support automatic cleaning?
Yes. It supports PLC-controlled automatic backwashing and automatic forward and reverse flushing. Chemical cleaning is performed manually.
Q4: What does the one-duty, one-standby arrangement mean?
It indicates that one unit operates while the other remains on standby, helping support continuity when the system is configured for alternating or backup operation. The exact switching sequence should be confirmed with the manufacturer.
Q5: Can the system remove bacteria and viruses?
Ultrafiltration membranes can remove many bacteria and some viral particles, depending on membrane characteristics and integrity. Actual removal performance must be confirmed through membrane specifications and validation; ultrafiltration alone should not be assumed to guarantee complete virus removal or disinfection.
Q6: Can the HDNUF-6000L be used before reverse osmosis?
Yes. Hollow fiber ultrafiltration is commonly used as RO pretreatment to reduce colloidal and suspended-solid loading. Suitability depends on the feed-water quality and the required pretreatment design.
Q7: What materials are used in the equipment?
The source specifies stainless steel construction and SUS304 sanitary pneumatic butterfly valves. The exact material grades of all wetted components should be confirmed for applications with strict hygiene or chemical compatibility requirements.
Q8: What pump protection functions are included?
The specified protections include low-water or dry-run protection, overload protection, overtemperature protection, and overcurrent protection.
Q9: What capacity and operating pressure does the system support?
The supplied description does not state rated flow or operating pressure. Contact the manufacturer for these values and the corresponding membrane configuration.
