It depends on your requirements for filtration accuracy, fluid flux, and pollutant capacity. The accuracy of the sintered metal powder filter is higher by 0.2-20 μ m, and the hardness is stronger; Although the accuracy of the sintered wire mesh filter is lower, ranging from 5-200 μ m, it has low fluid resistance, high porosity, larger dirt capacity, and is easier to clean.
There are three main cleaning methods for sintered metal filters:
- Backwashing/Backblowing: Suitable for automated online cleaning, can remove surface filter cake.
- Ultrasonic Cleaning: Suitable for deep filtration filters such as powder sintering, which need to be removed from the filter for cleaning.
- Chemical Cleaning: Suitable for deep regeneration with strong adhesion, chemical scaling, or organic polymer blockage.
Most sintered metal filters can handle pressure differentials of 3-5 MPa, while a few high-pressure resistant sintered metal filters can achieve pressure differentials of up to 20 MPa.
