1. Ultrasonic cleaning method
By using longitudinal waves to act on the cleaning solution, a certain number of sufficiently small vacuum bubbles are generated. When these vacuum bubbles cannot withstand pressure, they will burst and rely on the generated impact force to achieve flushing of the stainless steel filter element.
2. Baking cleaning method
This method is currently not widely used in most industries, so it will not be repeated here. As you all know, having this method is sufficient.
3. Reverse water cleaning method
This method is sometimes referred to as backwashing, which uses inert gas such as nitrogen to backwash in the opposite direction to the stainless steel filter element.
4. Solution cleaning method
Soak the stainless steel filter element in a 5% sodium hydroxide solution or nitric acid solution for 1 hour. The soaking time can be appropriately extended or shortened according to the degree of contamination of the stainless steel filter element, and then the filter element can be dried with clean air.
