Abstract: A filtering device for the removal of arsenic from the ground water/surface water. The filtering device of the present invention uses steel wool and sand as the raw material for the removal of arsenic from water and the entire outer body of the device can be made form cheaper material like plastic material or stainless steel. The filtering device of the present invention works on the simple principle of co-precipitation of arsenic with metals, followed by adsorption and filtration through treated sand. The metal, the steel wool, used in the device is a processed waste generated from steel plant thereby making the device extremely cheaper and versatile. Ih the filtering device of the present invention, iron arsenate and iron arsenite are co-precipitated by the reaction of steel wool with arsenic in water. The device uses treated river and simultaneously for the removal of iron leached out during reaction.
