Cleaning of Pall ring packing?
Thread Content
Are there any good ways to clean it? During the major maintenance, it is planned to remove the Pall ring packing for cleaning. How do people usually clean it? Is it necessary to have a cleaning tank? I’ve seen some manufacturers simply unload the items on the ground and clean them with high-pressure water guns – are there any better methods?
What I’ve seen is that a pool is created on the ground, and the filler is poured into that pool for cleaning!
What was mentioned above is the simplest method, but it isn’t guaranteed to clean everything thoroughly. One can make a device similar to a polisher, with a grid, that uses a high-pressure water gun while rotating.
Check how much filler there is? If the amount is small, use a concrete mixing bucket to mix coarse sand with water, then pour it out after some time. Rinse with water. This ensures cleanliness. If there is a lot of filler, it’s better to use high-pressure water for cleaning
However, with this method, it depends on the material of the filler
The wastewater generated by high-pressure water gun cleaning is difficult to treat; it is usually dumped into a large tank and then retrieved later
