Technical terms of filtering technology
Filtration : Liquid (Air) with impurities influent pass through the micropore of porous media,impurities are stopped in the media, thereby ,particles and liquid (air) are separated .
Filter Cartridges: It could be called also filter element or cartridge filters , the media made of a lot of materials to filter liquid or air which are installed in filter housings and take most important role in the processes of filtration .
Differential Pressure: The difference of pressure through any two points of a system or element.
Disposable: A filter after used and at the end of its service life could be discarded ,non-pollution and environmental.
Effective Area: The total area of the filter medium which is valid to fluid flow.
Efficiency: The capability of a filter to wipe off impurities contaminant at a given contaminant concentration under specified test conditions. Measured as a percentage.
Flow Rate: The volume of liquid across a filter at a certain time
Washable: A filter when become dirty with some contaminant can be washed or cleaned,and then continue to service with excellent dirt holiding ability .
Pleated: A filter cartridge which media be folded and made the form as a cylinder, cone, disc, plate, etc.
Housing: A tank enclosure which filters are installed and directs the flow of fluid through the filter element.
Absolute Filtration Rating: More better filtering effect ,higher percentage to remove the particles meet the demand of filter liquor in system .
Maximum Pressure: The maximum pressure that a filter could support without deformation or breakdown .
Maximum temperature: The maximum temperature that a cartridge could bear without spoiled or melt.
Permeability: The relationship of flow per unit area to differential pressure across the filter medium
Pore: A small hole in a filter medium allows fluid to pass by.
Rated Flow: The optimum flow rate for a filter which is designed for fluid filtration
ID: The inner diameter of a filter cartridge
OD: The outter diameter of a filter cartridge
Element: The porous media that have vital function the filtration process .
Welded: A method to make filter bags which joint filter felt or with plastic top ring together , also called hot melt.
Sewing: A way to manufacture filter bags which stitch filter fabric with top ring
PP Melt Blown Filter: A type of filter , some people also get usde to call spun filter/cartridge, PP Filter and so on .
String Wound filter: one kind of filter cartridge, also could be called wound filter/cartridge , wound yarn cartridge or spiral wrapping filter ect.
Central Core: A center pole in filter element , could be made of polypropylene or stainless steel , as the framework , it is important for increase the endurance of pressure in filtering system
Big Bule Filter: A bigger outter diameter of filter , generally speaking, OD is 4.5 inch of the filter .
Micron: The precision/rating of a filter ,use micrometer to express the measurement of the pole in filter medium
