Also known as pre-filtration, Coarse Filtration, is a process where the main objective is to remove coarsesuspended solids that could deposit on process equipment creating scale and corrosion sites.
It is mainly done to the source water before entering the main process itself. Filtration with coarse filters can typically range from less than 50 microns to 2000 microns. Filter cleaning is accomplished using automatic backwashing, and is required when the differential pressure on the unit increases to the point of maximum or the flow becomes too restricted.
