Deutsch: Filter
In the industrial and industry context, a filter is a device or system that is designed to remove or separate unwanted substances or impurities from a fluid, gas, or material. Filters are used in a wide range of industrial applications to improve the quality, purity, or safety of products and processes.
Examples of filters in industry include:
-
Liquid filters: Liquid filters are used to remove impurities from liquids, such as water, fuels, and chemicals. Examples include sediment filters, activated carbon filters, and reverse osmosis systems.
-
Air filters: Air filters are used to remove impurities from air, such as dust, pollen, and pollutants. Examples include HEPA filters, electrostatic precipitators, and bag filters.
-
Fuel filters: Fuel filters are used to remove impurities from fuels, such as gasoline, diesel, and aviation fuels. Examples include particulate filters, water separators, and coalescing filters.
-
Oil filters: Oil filters are used to remove impurities from lubricating oils, such as engine oil, hydraulic oil, and compressor oil. Examples include full-flow filters, bypass filters, and centrifugal separators.
-
Gas filters: Gas filters are used to remove impurities from gases, such as natural gas, propane, and oxygen. Examples include coalescing filters, activated carbon filters, and adsorption filters.
-
Particulate filters: Particulate filters are used to remove solid or liquid particles from fluids or gases. Examples include fabric filters, ceramic filters, and cyclone separators.
-
Chemical filters: Chemical filters are used to remove impurities from chemicals, such as acids, bases, and solvents. Examples include ion exchange resins, activated alumina, and zeolites.
-
Microbial filters: Microbial filters are used to remove microorganisms from fluids, such as water, pharmaceuticals, and biopharmaceuticals. Examples include ultrafiltration membranes, sterilizing filters, and virus filters.
