title: Development of a rapid infiltration system for wastewater and river water treatment in Japan using granulated materials.
abstract: A rapid infiltration (RI) system using granulated materials was developed for wastewater and river water treatment. Granules were processed by optimized procedures from soil and waste materials with high sorption of recalcitrant dissolved organic matter (DOM) and phosphorus. Granule performance was examined by laboratory column and pilot-scale tests. During the first year of the pilot test, removal of phosphorus was removed from livestock-farm effluent at the hydraulic loading rate of 2 m/day was 50-70% and that of refractory DOM was 10-30%.
