Liquid filters remove solids from liquids by flowing the contaminated liquid through a filter medium that will retain the solid particulates and allow only clean liquid to pass through. A liquid filter is designed to remove impurities that occur in liquids, both from natural and unnatural sources. Liquid filters are porous mechanisms that enable filtration systems to remove solid particles from a fluid stream. Industrial processes rely on various fluids which can easily get contaminated by unwanted solids during various stages (e.g. during initial mixing or after certain chemical reactions). Liquid filtration is a common method for clearing critical liquids of such unwanted material.
