Langmuir sorption isotherm was used to screen various substrates for use in removing phosphorus (P) in constructed wetlands (CW). The nine tested substrates included four sands, two soils, bentonite, and two industrial by-products of furnace slag and fly ash. Results showed that the furnace slag had the highest P sorption capacity (8.89 g Pk g(-1)), followed was the fly ash (8.81 g P kg(-1)), and that of sand II was the lowest. Different kinds of sands also showed varying P sorption capacity (0… CONTINUE READING
