Abstract (en)

[origin: WO2007052085A1] Method for treating underground waters (1) for removing arsenic. Said method is remarkable in that a biological oxidation of iron and manganese from the underground waters is performed during which the soluble iron and manganese are oxidized in the presence of iron and manganese oxidizing bacteria, characterized by the amorphous hydroxides and hydroxyoxides of iron and manganese which are formed and which on passage through a bed (4, 5) with a filter medium are removed from the water and gradually form a coating on the surface of the filter medium, thereby performing about a change in the properties of the filter medium which can simultaneously act as an adsorbent when it can also remove the arsenic by adsorption through a biological adsorption filtration.
