Electrocoagulation (EC) is becoming a popular process to be used for wastewater treatment. The removal of COD and turbidity from wastewater by EC using iron (Fe) electrode material was investigated in this paper. Several working parameters, such as pH, current density, and operating time were studied in an attempt to achieve a higher removal capacity. Wastewater sample was made from milk powder with initial COD of 1140 mgL-1 and turbidity of 491 NTU. Current density was varied from 3.51 to 5.62 mA cm-2, and operating time of between 30 and 50 minutes. The results show that the effluent wastewater was very clear and its quality exceeded the direct discharge standard. The removal efficiencies of COD and turbidity were high, being more than 65 % and 95 %. In addition, the experimental results also show that the electrocoagulation can neutralize pH of wastewater. =================== Elektrokoagulasi (EC) merupakan suatu proses yang populer untuk digunakan pada perawatan air sisa. Penyingkiran COD dan kekeruhan daripada air sisa oleh EC yang menggunakan material elektrod besi (Fe) telah diselidiki dalam kertas kerja ini. Beberapa parameter, seperti pH, kerapatan arus dan masa perawatan dikaji dalam percubaan untuk mendapatkan kadar penyingkiran lebih tinggi. Air sisa dibuat dari tepung susu dengan nilai awal COD 1140 mgL-1 dan kekeruhan 491 NTU. Kerapatan arus divariasi dari 3.51 hingga 5.62 mA cm-2, dan masa perawatan antara 30 dan 50 minit. Keputusan kajian mendapati bahawa efluen air sisa sangat jernih dan sesuai dengan piawai pelepasan. Efisiensi penyingkiran COD dan kekeruhan adalah tinggi, menjadi lebih dari 65 % dan 95 %. Sebagai tambahan, keputusan kajian juga mendapati bahawa elektrokoagulasi dapat meneutralkan pH air sisa.
