How to clean the filter element

Filter media type:
Wire Mesh-A fine fine metal mesh medium in which the warp and weft alternately pass through two or less threads, and the diameter of the warp is larger than the diameter of the weft. Wire mesh is a surface filter medium.
Porous sintering-where metal powder is pressed and sintered to form a porous material for deep filtration. Porous sintered material is a filter medium for deep filtration.
 
Cleaning process:
Screen filter:
Before cleaning: The parts should be hand-washed with liquid detergent or the like. Use acetone or IPA (isopropyl alcohol) to remove grease.
First rinse: The parts should be rinsed with filtered non-deionized water to remove any detergent or solvent residues. In this step, deionized water rinsing is acceptable, but not mandatory.
Ultrasonic cleaning: Immerse the parts in a degassed heated (105°-140°F) cleaning solution for not less than 30 minutes. Use OCC (octagonal) for random metal fiber elements.
Second rinse: parts to be rinsed with deionized water to remove any cleaning fluid
Pre-drying (if necessary): To speed up the drying speed of deionized water, please immerse PIECE in IPA (isopropanol) desiccant.
 
Porous sintered filter:
1: Determine what contaminants are in the filter
2: Determine the chemical reagents that will dissolve these pollutants (do not dissolve or attack porous metals)
 
Chemical reagents compatible with 316 / 316L stainless steel porous media include but are not limited to:
Water at any temperature
Liquor
acetone
ammonia
Organic solvents
Dichloromethane
Industrial cleaner
Solvents and cleaners
