Summary: Arsenic is a highly toxic metal found in drinking water in parts of Australia and in many parts of the world. The enforcement of stringent arsenic standard for drinking water calls for an effective treatment technology. In this study, an innovative and cost effective treatment system for arsenic removal will be developed for use in small community water supplies. This novel hybrid system consists of buoyant media flocculator and a newly-developed metal oxide coated media adsorption technique to achieve superior arsenic removal. A simple and safe disposal of arsenic sludge will also be established and tested.''
