  • Coagulation Filtration Arsenic in Drinking Water

    2015-7-17 · The filtration step can be accomplished using either media filters or micro-filters. The iron hydroxides adsorb the arsenic and the resultant solids are filtered out in the pressure filter vessel. The removal of the chemical solids is easier than removing turbidity solids from surface water, and therefore higher filtration rates can be used.
