Sintered metal filter
Filter type
Filtration and Filter
“Filtration” is the operation of separating solid stuff from a liquid or gas by passing a mixture of a solid in a liquid or gas through a filter medium with many fine holes.
The tool that performs this operation is the “filter”.
Filter classification
There are two types of filters, a depth filter and a screen filter.
The depth filter captures the object internally, and the screen filter captures the object on the surface.
Screen filters also include membrane filters, ultrafiltration filters, dialysis membranes and reverse osmosis membranes.
Filtration classification
Depending on the filter used, there are “coarse filtration”, “microfiltration”, “ultrafiltration” and “reverse osmosis”.
| Filtration | Size | Filter classification | Filter use | Captured stuff (e.g.) |
| coarse filtration | > 10μm | a depth filter | Pretreatment to prevent filter clogging | Algae, Fungi, Pollen etc. |
| microfiltration | 50nm – 10μm | a membrane filter | Sterilization operation | Bacteria (E. coli), etc. |
| ultrafiltration | 1nm – 50nm | an ultrafiltration filter | Fractionation and concentration with a molecular weight of 1,000 kDa or less | Hemoglobin,Virus, etc. |
| reverse osmosis | < 1 nm | dialysis membranes and reverse osmosis membranes | Water purification, etc. | Glucose, etc. |
Experiences of manufacturing sintered filters
Sintered filter
Sintered metal (= porous metal) is the product manufactured by the powder metallurgy method (, which is the manufacturing method in which metal powder is molded and sintered to make a metal product). A product in which the sintered metal is made porous and all the pores are connected is a sintered metal filter.
The names “sintered metal”, “sintered filter”, “sintered metal filter”, “sintered metal element”, “sintered element”, and “porous metal” are all the same product.
Features of sintered filter
It has the following characteristics.
- High mechanical strength and pressure resistance
- Excellent heat resistance and corrosion resistance (against acids, alkalis and chemicals)
- High-precision filtration capability
- Uniform filterability
- Mute effect capability to absorb sound energy
- Capable to be used repeatedly (by cleaning)
