Principle of Hollow Fiber Ultrafiltration Membranes and Maintenance Methods
Compared to traditional separation methods, hollow-fiber ultrafiltration technology operates at ambient temperature under mild conditions that prevent degradation of sensitive components. This makes it particularly well-suited for separating, fractionating, concentrating, and enriching heat-sensitive substances such as enzymes and fruit juices. Ultrafiltration boasts high separation efficiency, making it highly effective for recovering trace components from dilute solutions as well as concentrating low-concentration solutions—both processes are environmentally friendly and energy-efficient.

Hollow-fiber ultrafiltration membrane The fundamental principle behind this technology is the use of an asymmetric microporous structure and a semi-permeable membrane medium, operating at room temperature with specific pressure and flow rates. Leveraging the pressure difference across the membrane as the driving force, it allows solvents and small molecules to pass through, while retaining larger substances and particles—such as proteins, water-soluble polymers, and even bacteria—on the retentate side. This innovative membrane separation technique achieves goals like separation, classification, purification, and concentration.

Ultrafiltration technology boasts high separation efficiency, proving highly effective in recovering trace components from dilute solutions as well as concentrating low-concentration solutions—both of which are critical applications. It is an energy-efficient and environmentally friendly separation technique.
Hollow-fiber ultrafiltration membrane Maintenance instructions:
1 Before filtration, the raw water must be treated with a disinfectant to eliminate bacteria and microorganisms, as these pathogens have a strong potential to contaminate the water—capable of producing additional impurities and foreign substances on their own. Additionally, it’s essential to maintain an appropriate residual chlorine level.
2 For the pre-filtration of solid particle suspensions, especially when the colloid content is high, use flocculation and sedimentation as a pretreatment. Otherwise, the operating pressure on the ultrafiltration membrane will increase, potentially leading to unnecessary damage.
3 Regular backwashing with quick rinsing and periodic chemical cleaning help maintain membrane cleanliness, ensure high-quality membrane treatment processes, and extend the lifespan of the membranes.
4 "Regular dynamic filtration is essential, along with discharging concentrated water—recycling rates depend on the quality of the source water."
5 When starting and shutting down the equipment, slowly ramp up and down the voltage to prevent sudden surges that could exert excessive pressure on the membrane, potentially leading to damage.
