The aim of this research was to investigate the potential EZ enzyme in treating leachate by removing boron and reduction of chemical oxygen demand (COD). Two experiments were carried out (1) using a conventional biological treatment method and (2) using a sequencing batch rector (SBR) with additional of EZ enzyme in both method. The purpose of the first experiment was to obtain the optimum concentration of EZ enzyme to be used in second experiment. Results showed that the optimum concentration of EZ enzyme was 50 ppm, with the reduction of COD and boron was up to 70%, with the initial values of both parameters were 373.8 mg/l and 25 mg/l respectively. In the second experiment, two reactors (R1 and R2) were used, where R1 is a control, while in R2, EZ enzyme was added and the initial values of COD and boron were 433mg/l and 34mg/l. Both reactors showed a reduction of boron and COD. However, R2 was more efficient in removing the parameters. The reduction rates of boron and COD removed in R1 were 57% and 30%, while 84% and 69% reduction were recorded for R2.
