  • Phosphorus recovery from sewage sludge using the Aquacritox supercritical water oxidation process

    Abstract Every person produces approximately 1.2kg/annum of phosphorous. This is typically conveyed to a wastewater treatment plant. In the United Kingdom, the annual phosphorus load from human sources which is present in wastewater is therefore approximately 72,000 tonnes. This would have a value in the region of US$168M per annum based on current market prices. This paper ...
