DOI Open Access

Description

<jats:p>Arsenic exists widely in the environment, and a lot of arsenic pollution is found in the groundwater of South East Asia. In order to make arsenic free water, we made a simple device. The device is mainly composed of an iron containing oxidation tank, settling tank and sand filter. The arsenic in the water can be removed by iron oxidation which is caused by aeration. The device can remove about 98% of the arsenic in the water using less energy, and be maintenance free for a long period.</jats:p>
