How to clean the filter elements

Hebei UBO is a professional manufacturer of stainless steel filter elements. Today we will introduce you to how to clean stainless steel filter elements.

Filter media type:

Screen – A fine, fine mesh medium in which warp and weft alternately pass under two and two lines, and the diameter of the warp is heavier than the west. The screen is a surface type filter medium.

Porous sintering - a filter medium in which metal powder is pressed and sintered to form a porous material for depth filtration. The porous sintered material is a deep type of filter medium.

Cleaning materials:

1. Filter deionized water

2. Octagonal oxygen cleaner (OCC or NOC)

3. Isopropyl alcohol (IPA) in accordance with ASTM D770-05

4. Acetone in accordance with ASTM D329-07e1

5. Dawn liquid detergent or general equivalent

6. Powder-free inspection gloves – purple nitrile gloves or equivalent gloves used in the final cleaning process

Cleaning process:

Screen:

1. Before cleaning: Parts should be hand washed with Dawn® liquid detergent or similar products. Use acetone or IPA (isopropyl alcohol) to remove grease

2. First rinse: Parts should be rinsed with filtered non-deionized water to remove any detergent or solvent residue. In this step, deionized water rinse is acceptable but not mandatory

3. Ultrasonic cleaning: Immerse the parts in degassed heating (105°-140°F) cleaning solution for not less than 30 minutes. OCC (octagonal) is used for random metal fiber elements.

4. Second rinse: parts to be rinsed with deionized water to remove any cleaning solution

5. Pre-drying (if necessary): To speed up the drying of deionized water, immerse the PIECE in an IPA (isopropyl alcohol) desiccant.

6. Drying technology:

Nitrogen (99.9% pure filtered nitrogen) is dried (if necessary): Parts should be dried using a nitrogen blow dryer to remove any deionized water or to wet the cleaning residue.

Conventional oven drying: The parts should be dried using an oven (212°-230°F) to remove any deionized water. The inlet of a conventional oven should be filtered to a greater level than the medium it is to clean.

RMF and porous sintered materials:

1: Determine which contaminants are present in the filter

2: Identify chemical agents that will dissolve these contaminants (do not dissolve or erode porous metals)

3: Immerse the element in a chemical reagent as needed, rinse it with clean filtered water or other compatible liquid, and then blow it out with clean air or steam.
