PENGARUH VARIASI ELEKTRODA DALAM MENURUNKAN KADAR BOD DAN COD LIMBAH CAIR KELAPA SAWIT

Abstract

Research has been carried out which aims to determine the test results of palm oil effluent samples on BOD and COD parameters before and after the electrocoagulation process using Al, Zn, and Fe electrodes. This research uses palm oil effluent from PTPN IV ADOLINA. The results of the BOD test before electrocoagulation were 243 i mg/l. The results of the BOD test after electrocoagulation with the Al electrode were 100 mg/l, the Zn electrode was i 66.8 i mg/l, and the Fe electrode was 121 mg/l. The test results for COD levels before electrocoagulation were 649 mg/l. The test results for COD levels i after electrocoagulation with Al electrodes were 350 mg/l, Zn electrodes were 178 mg/l, and Fe electrodes were 315 mg/l. From these electrode variations, i the best results were obtained for testing the levels of BOD a nd COD of palm oil l iquid waste on the Zn electrode.
