The objectives of this study are to investigate the effect of media(loess ball) on the removal efficiency of nitrogen and phosphorous conditions in the farm area. This process(F-STEP PROCESS) for wastewater treatment was the order of influent, anaerobic, oxic, anoxic, phosphorous absorption, and effluent. The conditions of influent wastewater were T-N ( 7.4 - 16.2 ppm ), NO3--N ( 0.8 - 5.6 ppm ), T-P ( 1.1 - 4.0 ppm ), PO4--P ( 0.9 - 1.8 ppm), COD ( 10.2 - 30.0 ppm ), and BOD ( 22.0 - 50.0 ppm ). The average efficiency of wastewater treatment were T-N( 80% ), NO3--N ( 96% ), T-P ( 66% ), PO4--P ( 78 % ), COD ( 77% ), and BOD ( 90% ). The pH range of effluent water was between 6.8 and 7.3 in the process step, respectively, and the effluent SS of last step were between 0.6 and 5.0 mg/L.
