A screen filter is a type of water filtration device used to remove solid particles from water by physically trapping them on a porous screen or mesh. It operates on the principle of mechanical filtration, where water flows through the screen while solid particles are retained on its surface.
Screen filters consist of a housing containing a screen or mesh cartridge with specific pore sizes designed to capture particles of a certain size. As water passes through the screen, larger particles, such as sand, algae, and debris, are trapped on the screen’s surface, while the filtered water passes through and exits the filter.
Screen filters are commonly used in irrigation systems, agricultural applications, industrial processes, and residential water treatment systems to remove suspended solids from water before it is used for various purposes. They are available in various configurations, including disc and cylindrical designs, to suit different flow rates and filtration requirements. Periodic cleaning or backwashing is typically required to remove trapped particles from the screen and maintain filtration efficiency.
