Characteristics of ultrafiltration filter

Author:Huamo Water treatment materials FROM:Water filter membrane manufacturer TIME:2022-04-23

Ultrafiltration is the whole process of membrane separation with screening as the separation principle and burden as the driving force. The filtration accuracy is in the range of 0.005-0.01 μm, which can effectively remove particles, colloidal solutions, pathogenic bacteria basic cushions and polymer organic chemicals in water. . It can be widely used in the separation, concentration and purification of substances. After all, the whole process of ultrafiltration is idling and practical operation at room temperature, which is especially suitable for separating heat-sensitive substances. It has excellent high temperature resistance, corrosion resistance and air oxidation resistance. Long-term continuous use.

First, the characteristics of ultrafiltration filter.

Ultrafiltration filter adopts vertical cross filtration method, which can be reasonably cleaned or reversed. Therefore, it has obvious performance different from other purification separation equipment.
1. High precision: completely filter pathogenic bacteria, rust, colloidal solution, biological macromolecular substances and other substances in the water, preserve the nutrients that are beneficial to health, and filter the biological and turbidity of the water.
2. Long service life: Because ultrafiltration filter adopts the principle of vertical cross filtration, automatic cleaning, and it is not easy to be dirty and blocked, so under normal use conditions, the service life of uf filter cartridge is 30-50 times that of ordinary water purifiers.
3. Large flux: It can meet the requirements of direct drinking, beauty and skin care, showering, eating, and daily cleaning at the same time.

4. Low cost: Due to the large flux of ultrafiltration filter, long service life and maintenance-free, the solution cost of one ton of filtered water is only about one yuan, which is much lower than other integrated water purification equipment.

Second, the composition of hollow fiber ultrafiltration membrane

Hollow fiber ultrafiltration membrane is a different semi-permeable membrane made of polymer materials with unique technology. It is in the shape of hollow capillaries, and the wall thickness is covered with microporous plates. Under the action of working pressure, the stock solution flows in or outside the membrane. , the solution or small molecular water in it can pass through the membrane and become ultrafiltrate by collection, while the polymer material and colloidal solution particles are blocked on the membrane surface and taken away by the stock solution circulating in the circulation system to become the extraction solution, so as to achieve The purpose of substance separation, concentration and purification.
