PENERAPAN METODE ELEKTROKOAGULASI DALAM PENGOLAHAN LIMBAH CAIR INDUSTRI KARET DENGAN MENGGUNAKAN ELEKTRODA ALUMINIUM

Application of Electrocoagulation Method in rubber Industry Wastewater Treatment by using aluminum electrodes (RA Sarah Noviatri, 2014, 60 pages, 2 tables, 11 images, 3 enclosures) 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 are 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 as metals, organic substances, inorganic substances, etc. For that we need a method that can be used in treating wastewater rubber industry that is the electrocoagulation method. A new method that can be applied in treating wastewater in Indonesia. Application of the method in treating wastewater electrocoagulation rubber industry is done by varying the high voltage and plate electrodes are immersed into the waste, the voltage variation are 18 V and 24 V with a height variation of plate electrodes immersed are 3, 6, 9, 12 and 15 cm the parameters include pH, turbidity, conductivity, TDS and DO. From the results, optimum conditions are at a voltage of 24 V with an electrode height of 15 cm, with a pH value of 9.05; conductivity of 638.6 microseconds; TDS of 488 mg / L; DO at 6.59 ppm; turbidity of 1.31 NTU.
