Electrocoagulation, Effect, Flow rate


The gold amalgamated wastewater flow can seep into the soil and partly lead to ditches and end into seasonal rivers. The waste contains several heavy metals, including Hg and Cu. In the rainy season, runoff can occur which dissolves pollutants in wastewater at the ground surface so that water can flow into sewers or will seep into the ground and heavy metals contained in a waste can contaminate groundwater. Thus, it is possible to contaminate the quality of surface water (rivers) and groundwater (wells) around gold processing and wastewater disposal sites. The purpose of this study was to determine the effect of flow rate as an independent variable in continuous electrocoagulation. This research was a laboratory scale and used gold processing wastewater from gold washing activities. Electrocoagulation in this study using a continuous reactor. Based on the results of the processing carried out by the continuous system electrocoagulation method. The discharge of Q1 (0.0156 m3/s) reduces the levels of TDS, pH, TSS, and Cu in wastewater greater than the discharge of Q2 (0.018144 m3/s). These results have also exceeded the TSS parameter quality standard which refers to the Decree of the Minister of the Environment No. 202 of 2004 about Quality Standards for Wastewater for Businesses and/or Mining of Gold and/or Copper Ore, so it is safe to dispose of into the environment.
