Ultrafiltration Technology Services
Ultrafiltration is a membrane separation process driven by pressure difference, and it is the most widely used membrane separation technology. In the food industry, ultrafiltration technology is mainly used in many operations such as pure water manufacturing, whey concentration and juice clarification. The classification of ultrafiltration is mainly based on the classification of ultrafiltration membrane components, which are mainly divided into roll type, plate and frame type, tube type and hollow fiber type.
Process Parameters Affecting Ultrafiltration
Liquid flow rate
Increasing the liquid flow rate is beneficial to reduce the concentration polarization and increase the permeation flux.
Operating Pressure
The relationship between permeate flux and operating pressure of ultrafiltration membrane depends on the nature of the membrane and gel layer. Only when the operating pressure reaches a certain level in the ultrafiltration process can the small molecules in the liquid be separated through the membrane.
Operation cycle
As the ultrafiltration process proceeds, a gel layer gradually forms on the membrane surface, causing the permeate flux to drop.
Feed concentration
As the ultrafiltration process proceeds, the concentration of the main stream gradually increases, and the viscosity becomes larger at this time, which increases the thickness of the gel layer and thus affects the permeate flux.

Characteristics of Ultrafiltration Technology
- The ultrafiltration process does not undergo phase change, no heating is required, energy consumption is low, no chemical reagents are added, and there is no pollution.
- The ultrafiltration process can be carried out at room temperature under mild conditions without component destruction, and is therefore particularly suitable for heat-sensitive substances.
- The ultrafiltration process uses only pressure as the driving force for membrane separation, so the separation device is simple, the process is short, easy to operate, and easy to control and maintain.
- Ultrafiltration technology has high separation efficiency and is very effective for the recovery of trace components in dilute solutions and the concentration of low concentration solutions.
- Ultrafiltration throughput is influenced by feed flow rate, operating pressure, temperature, operating cycle, feed concentration, pretreatment of the feed solution, membrane cleaning, ultrafiltration membrane pore size and elution volume.
