What Is a Filter Cartridge?
A cartridge filter is a key component in filtration systems, used to separate the desired and undesired components of the process stream. They allow fluid flow while capturing particles. Commonly, they are used to separate solids from liquids or gases.
Filtration cartridge can be made from various types of materials such as a) Polymers (Polypropylene, PTFE, Nylon, etc.) b) Metals (SS316, Hastelloy C22, Hastelloy C276, Fe3Al, etc.), c) Ceramics (SiC, Mullite, Alumina, etc.), and d) Glass. Each filter cartridge has a specific porosity rating, which is a function of its manufacturing process. This porosity is what gives the cartridge filter its filtration capabilities. Over time, particle accumulation in the pores may lead to clogging, requiring replacement or cleaning based on the cartridge type.
Cartridge filters are widely used in water purification, Solvent filtration, Steam filtration, amongst other industrial processes. In the pharmaceutical industry, they may be used for filtration in process streams which require sterility. Validated membrane filters must be used in such critical applications.
What are different types of filter cartridges?
Cartridge filters are available in various types, depending on their material of construction (MOC) or their manufacturing process. Each filter cartridge is designed specifically to fulfil filtration requirements
