Questions about filtration equipment
Thread Content
The reaction suspension I am currently dealing with has a solid content of around 0.2%, and a total of 6 tons need to be processed within 24 hours. Previously, microporous filters were used for this purpose; however, due to the large volume of material to be processed, filtering becomes difficult after a certain point. This is because there is a substance called phospholipid in the liquid, which is highly viscous, and once it accumulates to a certain amount on the filter elements, filtering becomes extremely difficult, thereby severely affecting the continuity of production. I would appreciate any advice from those with more experience regarding effective methods and suitable equipment that could be utilized in this situation.
Check what reagents can be used to remove the phosphate salts from the surface; moreover, such a reagent should be able to remove the substances on the surface without damaging the equipment. This way, the equipment can be cleaned periodically, ensuring excellent filtering performance!
Thank you for the advice. Using reagents is one method, but after treatment I have to deal with the waste reagents, which poses an environmental issue. We have also considered adding filtering agents such as perlite or silica gel to the suspension; however, this needs to be tested to ensure it does not affect the quality of the product； It will also increase the amount of waste and solid waste, which is something that needs to be taken into consideration.
Could backwashing be used to wash away the viscous substances before proceeding with filtration?
Reply to 4# haohan1982: There is a method for backwashing in microporous filters; this function exists because the particles being filtered are extremely fine and remain inside the sintered rods, making it difficult to remove them through backwashing. Previously, it was necessary to stop the filtering process and use a solvent for washing in order to remove these particles, which was a time-consuming process. ,
Hello, we have a self-cleaning filter that can handle viscosities up to 1,000,000 centipoise; it should be able to solve your current problem without the need for any additives, and it automatically removes debris. I hope you will get in touch with me to provide me with your detailed technical requirements, so that we can offer you the most suitable product.

For this issue, I think a hierarchical filtering approach can be considered. For materials with high viscosity, coarse filtration is generally sufficient to remove most of the impurities; for example, bag filtration or chamber filter presses can be used for coarse filtration, followed by fine filtration using microporous filters. A backwashable device is necessary, and high pressure is required, with pulse operation yielding better results
It’s too professional; I don’t understand it. Anyway, I have box filter presses, plate and frame filter presses, and diaphragm filter presses here. I know about filter presses!
