This study applied one chemical coagulant, PAC, and three biological coagulant aids include Moringa seed gum, Cassia seed gums and polymer. The results indicated that the best dose of PAC be used as coagulants was 480 mg/L. Using polymer as aids with PAC could remove 66.70 % of COD, 66.86 % of SS, 39.01 % of color from studied wastewater. Using Moringa seed gums as aids with PAC could remove 69.34 % of COD and, 69.61 % of SS, 36.25 % of color from studied wastewater. Similarly, using Cassia
