Porous metal membranes are often used in operations such as separation, purification, and concentration. Because of its excellent characteristics, it has been widely welcomed in more and more industries.
What are the advantages of porous metal membranes?
(1) It has good machining performance, welding performance and sealing performance;
(2) Due to the high mechanical strength, it can be used under higher pressure (withstand pressure up to 31MPa), so the method of increasing the pressure difference can be used to increase the permeability and increase the separation ability of the membrane;
(3) It can withstand the working temperature of 315°C and has good thermal conductivity. The thermal stress in the membrane module is small, so the high temperature will not affect the life of the membrane material, nor will it damage the retention performance of the membrane, nor will it cause sudden failure of the membrane module. destroy;
(4) It can resist the corrosion of strong acid and strong alkali, can be used for the separation operation of extreme pH material liquid, has good adaptability to materials, and broadens the application field of membrane separation technology;
(5) Good sealing performance, good welding performance, and easy connection of membrane components;
(6) The cleaning and disinfection of the porous metal membrane is easy. The porous metal membrane can withstand the cleaning of strong acid and strong alkali without causing the deterioration of the membrane material, and the porous metal membrane equipment can be directly sterilized by steam, so as to ensure the safety of the equipment. Bacteria operation;
(7) The porous metal membrane can be used for the separation of high solid content or high concentration feed liquid, and the membrane pollution is very small;
(8) The service life of the porous metal membrane is long;
(9) It has strong application value. During the filtration process, the porous metal membrane has a large adsorption capacity, good support, large filtration area, and can be cleaned online without affecting production.
