Abstract
A single, mixed-bed column of Birm® over Filox® to remove iron and manganese, thereby protecting Filox®, the oxidizing media, from fouling by iron and manganese. This helps to remove iron and manganese to low levels so that As(III) may be oxidized to As(V) more efficiently before it is treated with adsorptive media.
