The effect of carbon steel-wool in removal of arsenic from drinking water

. This paper attempts to prove that the removal of arsenic in drinking water is a combination of the granular activated carbon and carbon steel-wool. The steel-wool filter is the most important in residential applications. The single most important consideration is the empty bed contact time. Removal of inorganic arsenic to parts per million (ppm) or parts per billion (ppb) levels within 15 to 30 min is fairly common. Immobilization techniques are likely to continue to gain importance in the world.
