Filtration and Separation Technologies
Porous materials are used as filters in many industries such as Chemical Processing, Semiconductor, Polymer Processing, Power Generation, Mining, Food and Beverage, Pharmaceutical and Petrochemical Processing. Applications such as recovery of catalysts, gel shearing and filtration of Nylon & Polyester Fibers and filtration of process gases and liquids are common industrial filter applications. Filters for protecting the nozzles openings in Oil Burners or other combustion equipment are critical to the operation of a burner and its efficiency.
Filtration and separation technology that require filtration of solid particles between 0.1 to 100 micrometers, require superior mechanical properties and need excellent corrosion resistance at higher temperature and pressures are good candidate applications for porous sintered metals. Porous metals offer absolute particle retention, have rigid pore structures, are cleanable and will not shed particles. These properties are often critical to the filter system operation. Porous metals can also be used as supports for weaker polymeric membranes or coated with other materials to offer even finer filtration properties.
Material, Micron Grade and Dimensions are normally specified for general filtration applications, but there are often additional specifications, such as flow rate and density, required to meet more demanding applications.
