Ultrafiltration membrane

Product Overview

Ultrafiltration membrane is a kind of polymer semipermeable membrane used in the ultrafiltration process to separate polymer colloids or suspended particles of a certain size from the solution. [2] With pressure as the driving force, the membrane pore size is 1~100nm, which is an asymmetric membrane type. The pore density is about 10/cm, and the operating pressure difference is 100~1000kPa, which is suitable for removing colloidal grade particles and macromolecules, and can separate solutions with a concentration of less than 10%.

Key features:

Ultrafiltration membranes have been widely used in the advanced treatment of industrial wastewater and process water, such as the concentration, purification and separation of macromolecular substances in the chemical, food and pharmaceutical industries, the sterilization of biological solutions, the separation of dyes in printing and dyeing wastewater, the recovery of glycerin in petrochemical wastewater, the recovery of silver in photochemical wastewater and the preparation of ultrapure water. In addition, it can also be used for sludge thickening and dewatering.

Fields of application

Surface water treatment, drinking water preparation, ultrapure water preparation, reclaimed water reuse, food concentration, oilfield reinjection water treatment, seawater desalination pretreatment, etc.

Technical features:

The ultrafiltration membrane has high chemical stability, acid and alkali resistance, low influent water quality requirements, and strong versatility;

The ultrafiltration membrane technology is simple in principle, easy to operate, easy to maintain, safe and stable in operation;

Ultrafiltration technology is a physical method, which does not need to add any chemicals in the water treatment process, which avoids secondary pollution of water bodies;

Ultrafiltration technology has high efficiency, large amount of water to treat, and high rejection rate of colloids, particles, bacteria, viruses, etc. in the water.
