Abstract
Main purpose of this study has been to obtain the optimum conditions for removing phosphorus from a waste water in a chemical way, by using Mg2+ ion. Study reached the following conclusion by applying different conditions, which influence on the formation of struvite, i.e. pH, molecule ratio of Mg2+ to NH4+ and the temperature. The optimum condition for precipitating struvite was found by examining the precipitate and pH and mole ratio of precipitator in recovery of struvite from filtrate. Optimum pH is "9" at the temperature of 40 ～70℃ and Optimum molecule ratio of Mg : N : P is 2.0 : 1.0 : 1.0. Settlement was proved to be a struvite by XRD analysis
