Zusammenfassung: | Industrial wastewater is one of the types of waste that can pollute the water environment. Almost the entire industry has one wastewater effluent owned rubber industry. Many of the rubber industry is less concerned about the quality of water and dispose of waste directly into the environment. Whereas in the rubber industry wastewater content, there are many pollutants that can harm the environment, especially the marine environment, such contaminants as metals, organic substances, and inorganic substances. For that, we need a method that can be used in treating wastewater of this rubber industry that is by electrocoagulation method. Electrocoagulation is a method of coagulation by using electric current through electrochemical events. Rubber wastewater treatment by electrocoagulation method is done by varying the voltage and process time, that is with variations of 12V, 15V, and 18V and with variation of process time 30 minutes, 60 minutes, 90 minutes, 120 minutes and 150 minutes to find out pH values, Total Suspended Solid (TSS), Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD

, and Ammonia levels. From the research results obtained, optimum conditions are at a voltage of 18 volts with a processing time of 150 minutes. The effectiveness electrocoagulation of rubber wastewater was for TSS 85.39%, COD 56.14%, BOD

73.5%, respectively. These results have fulfilled the environmental standards of rubber wastewater. |
