  • Phosphorus and Heavy Metal Extraction from Wastewater Treatment Plant Sludges Using Microwaves for Generation of Exceptional Quality Biosolids

    ABSTRACTThe objective of this study was to evaluate how much phosphorus and metals in sludge can be released into solution by microwave irradiation when applied to sludge prior to anaerobic digestion, and to determine the effectiveness of subsequent lime precipitation. For thickened sludge, the fraction of phosphorus in the soluble form increased to 23%~28% while for unthickened sludge, to ...

  • Study of oyster shell as a potential substrate for constructed wetlands

    We tested the suitability of oyster shell (OS) as a substrate for phosphorus removal in constructed wetlands (CWs) treating swine wastewater. OS is proven to have a significant phosphorus adsorption capacity; significant phosphorus removal was achieved in vertical subsurface flow constructed wetlands (VSSFs) that were filled with OS and used to treat swine wastewater. In the VSSF system, OS ...
