Abstract
Electroplating is a method of using electrolyte solutions to cover solid materials with metal layers. The strong metal waste from the electroplating process is contained in B3 waste (Hazardous Toxic Materials). One of the methods for electroplating is by combining filtration and electrocoagulation methods. The parameters observed in this study were total dissolved solid (TDS), pH, conductivity, and Cr and Ni electroplating wastewater content before and after treatment. This research was conducted by adjusting the processing time and the distance between the electrode plates. The cycle time is 30, 60, 90, 120 and 150 minutes with an electrode spacing of 1, 2 and 3 cm. This feedback is to the activated carbon filter and the silica sand by the electrocoagulation process using aluminum electrodes. The feedback is filtered with a cartridge filter and a reverse osmosis (RO) filter. The results show that the optimum TDS, pH, conductivity and levels of Cr and Ni occur at a processing time of 150 minutes at an electrode distance of 1 cm. The pH value rose from 5.63 to 7.89, and the TDS decreased from 234 ppm to 73.6 ppm. Conductivity also decreased from 1466 μs / cm to 148.5 μs/ cm. Cr and Ni have decreased from 8.43 ppm to 0.29 ppm and from 9.288 ppm to 0.893 ppm. The outcomes of this waste treatment met the requirements for clean water (Regulation of the Minister of Health of the Republic of Indonesia, No 32 of 2017) and industrial wastewater (Regulation of the Minister of the Environment of the Republic of Indonesia, No 5 of 2014).
