【 摘 要 】

Wastewater from the soft drink industry must be treated before release to reservoir. One of many treatments of wastewater is electrocoagulation method. Five litres of wastewater was agitated using a magnetic stirrer with the addition of bitterns in a tank electrochemical device. It was started by 100 rpm of agitation for 3 minutes and then the agitation was decreased to 50 rpm for the certain time. The filtrate was separated and analysed Chemical Oxygen Demand (COD) and BOD. Percent of COD removal tends to increase with the length of the electrocoagulation process and vice versa for BOD. Different things occur in percent COD and BOD removal, where the best percent removal is obtained at 0.5% bitter addition. The highest percentage of COD removal reached 98.31% at 6 hours and the highest percent of BOD removal reached 95.00% within 2 hours.
