This study includes pretreatment process with coagulation and post treatment to determine the optimum dose of ZnO photocatalyst, optimum pH and the reaction rate constant (k). The result showed that the pretreatment process using coagulation with Al2SO4 at 110 ppm dose, and pH 6,5 with the percentage of removal for turbidity, color and TSS are 89%, 78%, and 98%, respectively. Photocatalysts process showed that the optimum condition of color substance degradation in peat water requires 0,5 g/L ZnO, pH 4 and UV radiation for 120 minutes. Photodegradation rate constant of 0,0209 min-1 and the percentage of degradation is 20,54%. The peat water before treatment has color substance concentration can be set aside for 527 Pt.Co to 10 Pt.Co with the combination of coagulation and ZnO photocatalyts process.<p align="justify"> text |
