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 RatingMore 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
