The purpose of this study is to evaluate for performance of biochipfiltration phosphorus treatment process developed by ANT21 and to enhance phosphorus water quality standards to meet the optimum operation conditions of phosphorus treatment process are presented. Alum, FeCl3 as the coagulant used, each with a Jar-Test influent water quality and remaval efficiency of phosphorus treatment process when compared to water quality and removal efficiency of T-P are not a big difference, Alum in the removal efficiency and water quality was the most stable and high coagulant in the case of the removal of CODmn, SS, TN. Alum and Polymer processing efficiency when using the water quality was good and treatment water quality is CODmn 19 mg/L, SS 5 mg/L, TN 26 mg/L, T-P 0.135 mg/L less than water quality standards. If Alum is applied to the field, Alum injection amount per m3 influent unit is 24 g. During the field testing operation period, the influent has average COD mn 27 mg/L, SS 10 mg/L, T-N 22 mg/L, T-P 0.910 mg/L, and the final effluent has average CODmn 22 mg/L, SS 4 mg/L, T-N 20 mg/L, T-P 0.166 mg/L respectively. Average removal efficiency of each water quality item was CODmn 21%, SS 65%, T-N 8%, TP 82% and phosphorus treatment process is effective for the removal of SS and T-P but there is a limit to the removal of CODmn and T-N.
