How is the suspension separated after polymer demulsification and coagulation? How to choose a filter screen/fabric to prevent clogging?
Thread Content
After the polymer emulsion is demulsified, a suspension is formed. How can solid-liquid separation be carried out? The solid content of this suspension is 10%, and the particle size ranges from 30 to 50 microns. What type of filtration device should be used? How should the filter cloth or filter screen be selected to ensure that the screen does not get clogged?
Hello! Could you please explain the filtering medium in more detail? Based on your current description, it seems quite simple – it’s a filter for separating solids from liquids, whose main function is to remove impurities. As for the issue of clogged filter elements, one should try to choose filtering materials with a long service life; filter elements are consumable items, and there are none that can never need to be replaced.
Thank you for your reply. We need to separate the hydrophobic polymer particles from water, and after separation and dehydration, the particles should not be compressed into a compact mass; they should remain in their original paste form with a size of 30–50 um
