filter rod

What are good ways to keep the filter rods clean and clear? Materials tend to precipitate out, and the filters are meant to remove insoluble impurities. Soaking doesn’t help to clean it thoroughly, nor does blowing with nitrogen or rinsing with water.
The filter rod should be made of stainless steel; if ordinary soaking doesn’t work, use an acidic medium for soaking
This component is called a filter element. In most cases, fluid flows in from the outside and out from the inside. First, it’s necessary to check whether the filter element can be cleaned. Some filter elements are disposable – once they become clogged, they cannot be cleaned, such as those made of glass fiber, polypropylene, PTFE, etc. Others can be cleaned, like those made of metal; however, there are specific methods for cleaning them, such as immersion, ultrasonic treatment, or high-temperature treatment. Even for filter elements that can be cleaned, their filtering efficiency may decrease or the pressure difference may increase after cleaning, as cleaning them does not achieve the same results as using a new filter element
That’s right, steel filter rods can be cleaned. As for non-metallic ones, it depends on the fluid being filtered; for fluids with low requirements or water-based fluids, they can sometimes be cleaned 1 or 2 times； Even after processes such as soaking, pickling, and ultrasonic cleaning, the regeneration rate of the filter pores in metal filters is not 100%; there are always pores that cannot be cleaned. As the number of cleaning cycles increases, the regeneration rate of the filter pores decreases accordingly ； The metal filter element needs to be replaced not because it’s broken or damaged, but because the filtration pores have become so clogged that they can’t be cleaned, which affects production; therefore, a new filter element must be used
