[Treatment process] Filtration [Contaminants Removed/Altered] Iron, manganese, arsenic, silt, sand, organics, some heavy metals, radon, cysts [What it does] 
By passing water through a cartridge, granular media or other device, contaminants are subtracted from the water to make it cleaner. In some cases this is a "straining" effect; in other cases the contaminants are removed by adsorption- the contaminants have an attraction to the surface of the filter. Often, minerals such as iron and manganese are oxidized prior to filtration in order to create large enough particles to filter. In addition, pH changes may be needed.
