Ultrafiltration is a separation membrane process that uses screening as the separation principle and burden as the driving force, with a filtration accuracy of 0.005-0.01 μ Within the range of m, it can quickly eliminate particles, colloidal solutions, bacteria, pyrogens, and organic chemical substances in polymer materials in water. The entire process of ultrafiltration, after all, involves air conversion and practical operation at room temperature. It is particularly suitable for the separation of thermosensitive substances and has good resistance to high temperature, acid and alkali, and air oxidation. It can be used for a long time under conditions of 60 ℃ and pH 2-11.

The methods of ultrafiltration membranes can be divided into two types: flat and horizontal. Tubular ultrafiltration membranes can be divided into hollow fibers, capillaries, and tubular membranes according to their differences in tube diameter. The ultrafiltration membranes used for wastewater treatment in the market are mostly capillary type, and the commonly used hollow fiber (nominal diameter 0.1-0.5mm) PE or polypropylene microporous membranes in some engineering projects should actually belong to hollow fiber membranes.

The components that can connect the ultrafiltration membrane filaments to the ultrafiltration system software are called ultrafiltration membrane components. Ultrafiltration membrane components are divided into three types: internal pressure, external pressure, and immersion. The driving force for submerged ultrafiltration membrane filtration is the pressure difference between the vacuum pump inside the membrane tube and atmospheric pressure. For ultrafiltration membranes with high filtration accuracy requirements, this pressure difference is generally difficult to meet the demand for filtration driving force. Therefore, the submerged component method is more suitable for ultrafiltration membranes or hollow fiber membranes with relatively low filtration accuracy. External pressure ultrafiltration has extremely uneven liquid flow velocity on the surface of the membrane during forward and reverse forces, which endangers the actual cleaning effect of the membrane surface. Therefore, ultrafiltration membranes or internal pressure components mainly used for sewage treatment have more advantages in construction.

Characteristics of ultrafiltration water treatment equipment:

1. The selection of ultrafiltration membrane components from global membrane companies ensures that customers receive high-quality organic chemical membrane components from around the world, thereby ensuring the interception performance and membrane flux.

2. The system software has a high utilization rate and produces high-quality products, which can achieve efficient separation, purification, and high rate extraction of materials.

3. There is no change in the processing, and there is no negative impact on the composition of the raw materials. The separation, purification, and extraction processes are always at room temperature, which is particularly suitable for the treatment of thermosensitive substances. This avoids the disadvantage of high heat damaging physiological active substances and reasonably preserves physiological active substances and nutrients in the field of raw materials.

4. The system software has high efficiency, short production cycle time, and compared with traditional process technology, the operating cost of machine equipment is low, which can effectively reduce costs and improve enterprise efficiency.
