Questions about plate filters
Thread Content
A friend’s factory uses plate filters to purify oil, and they’ve found that the pre-coating with diatomaceous earth isn’t very even, which affects the filtering efficiency. Could someone explain the possible reasons for this? It would be great if I could get contact information for relevant manufacturers or organizations that offer technical support. Thank you!

The problem is that not only is the thickness uneven, but in some areas the pre-coating doesn’t work at all; this is the key issue! I tried various methods and found that sometimes pre-coating can function as a filter cake, while at other times there are areas without pre-coating. I searched through various sources but found no relevant information, which is why I’m seeking advice from everyone~
It’s best to contact the engineering company that designed and built your oil refinery; they provide technical support after installation. In your case, it’s likely not a problem with the plate and frame filter. We are also an oil processing engineering company, specializing in various processes such as pretreatment and extraction/refining. If you have any issues, feel free to contact us.
It is not very easy to establish a diatomite pre-coating layer on plate and frame filters; strict requirements are imposed on aspects such as the concentration of the pre-coating suspension, the pre-coating pressure, the holding time, and the uniformity of the filter fabric, and reliance can only be placed on experience
How can I get in touch with your company? I’m also checking for information on behalf of my friend; could you give me a way to get in touch? Thank you~!
