Wastewaters containing phosphorus and nitric acid are produced during biological\ntreatment processes. In this study, a material for treating such waste waters\nwas developed. Foamed glass was produced from waste glass and then\nheated with iron sulfate to prepare an adsorbent for phosphorus and carrier\nfor reducing nitric acid. The adsorbent performance was evaluated in batch\nand continuous experiments. The saturated adsorption amount of phosphate\nwas 6.23 mg/g for the product obtained from glass of size 3 to 12 mm; the\namount adsorbed was relatively high, in spite of the large glass size. The denitrification\nby reduction of nitrate was around 25%.
