The main objective of filtration over granular materials is to retain the suspended matter contained in the water to be treated. Nevertheless, depending on the filtering medium used, it may also be used to oxidise dissolved metals (iron, manganese, arsenic, etc.), absorb organic matter or heavy metals, neutralise, obtain a catalyst effect (dechlorination), etc..
