Filtering issues
Thread Content
For silicone products with a viscosity of 50 cp and a solid content of 10%, which are sensitive to water, what type of filtration equipment would be suitable given a required filtration rate of 10 cubic meters per hour? ? ? We are currently using a box-type filter press model XAY-630, along with polyester filter cloth with a mesh size of around 1000. Cleaning this filter cloth is quite troublesome; after being used four or five times, the new filter cloth is essentially rendered unusable. . It won’t filter at all. .
In the process of producing nanoscale ultra-fine powders via wet chemical methods, it is necessary to wash the ultra-fine product slurry, which is rich in impurity ions, in order to improve its purity. Unlike traditional plate and frame filtration and centrifugal separation, ceramic microfiltration membranes primarily use cross-flow filtration for solid-liquid separation. The ultra-fine powder slurry continuously circulates on the circulation side; the membrane surface is capable of retaining the ultra-fine powder particles, while allowing impurity ions in the solution to pass through the membrane pores and escape. Since the fluid flow is parallel to the surface of the filtering medium, the filtration resistance is **reduced**, allowing a high permeate flux to be maintained at lower pressures, thereby enabling the filtration process to continue for an extended period of time. Key process features: Extremely high filtration precision, suitable for ultra-fine powder systems with excellent dispersibility; high retention rate for ultra-fine powders; simple operation; good cleaning efficiency, enabling the production of materials with a purity greater than 99%. 5% ultra-pure powder. The main body of the equipment is made of stainless steel or corrosion-resistant composite materials; there are few vulnerable components, making equipment maintenance simple. The process is stable, and product quality is easy to control
Imported filter cloths can be considered; the quality of these cloths has a significant impact on their lifespan. If you need any assistance, feel free to contact me at 13861322978
It is recommended to use bag-type backwash filters; our company can provide prototype tests. Feel free to contact if you’re interested
How about heating the filter plate for filtration? Can it come into contact with rubber and iron?
Reply to 2# baby_tree: What was said on the fourth floor is correct; using a centrifuge is the right choice.
I believe that centrifuges can handle liquids with a high solid content, achieving only a microfiltration level (25 microns or more); if higher standards are required, they will not be effective. Our company has developed bag-type backwash filters with a high solid content, addressing both the issue of high solid content and the requirement for high filtration precision.

As I mentioned, I am using a sedimentation centrifuge – it has nothing to do with filtration but is related to density. The sedimentation method has a wide range of applications and delivers excellent results!
Reply to 9# li*nji: Thank you for your advice; I’m working hard to learn
Filtering involves problems such as clogging and regeneration of the filtering medium, while sedimentation separation does not use any filtering medium!
