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
Sometimes also known as backwashing method, this method uses inert gas, such as nitrogen, to backwash in the opposite direction of stainless steel filter filtration.
4. Solution cleaning method
Soak the stainless steel filter element in a 5% sodium hydroxide solution or nitric acid solution for 1 hour. Depending on the degree of contamination of the stainless steel filter element, the soaking time can be appropriately extended or shortened. Then, dry the filter element with clean air.
