In order to comply with the new drinking water standard for arsenic of 10 my g/l, effective methods of removing arsenic are necessary. In a water treatment plant, suitable methods for the precipitation/flocculation by iron(III)-chloride and iron(II)-sulphate as well as adsorption on a newly developed granulated iron hydroxide were compared under practical conditions. Adsorption on granulated iron hydroxide proved to be the method which provided the greatest operational reliability while requiring the least maintenance and monitoring. The flocculation with iron(II) offered clear handling advantages over iron(III) because cf the significantly better filtration properties of the solids formed.
