SYSTEM FOR OXIDATION OF ARSENIC (III) IN GROUNDWATERS WITH HIGH IRON AND MANGANESE CONCENTRATIONS AND METHOD THEREFOR

摘要

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.
