S In order to recover ammonium, phosphate and potassium from swine wastewater as magnesium phosphates, the optimal condition was investigated using synthetic swine wastewater, and under the optimal condition, recovery experiment was performed using actural swine wastewatare obtained from an outflow of a septic tank. The optimal condition to recover ammonia, phosphate and potassium simultaneously was found to be a pH of 8.0, P/(N+K) of 1.5, and Mg/P of 1.5. This optimal conditions were applied to the actuarl swine wastewater, and NH4-N, K, and P were recovered at high recovery rates of 95%, 85%, and 90%, respectively.
