Abstract

PT Sipatex Putri Lestari is an industry engaged in the textile sector. In the production process, this industry produces alkaline wastewater and there are several parameters that exceed NAB including sulfides and colors. From the results of laboratory tests it was found that sulfide levels were 1.3 mg/l, the sulfide content of this wastewater exceeded the predetermined quality standard, which was 0.3 mg/l. The high levels of sulfide in waste water cause an unpleasant odor and can disrupt the concentration of employees in work and the color of the waste water after processing is still a little thick. The purpose of this study was to determine the differences in the electrocoagulation contact time of 30 minutes, 60 minutes and 90 minutes against the reduction of sulfides and colors in wastewater. The type of research used in this study was an experiment with the design of pre and post control. From the results of the ANOVA test it was found that the electrocoagulation process can reduce sulfide and color in wastewater (p value <0.05). Electrocoagulation contact time 30 minutes, 60 minutes, 90 minutes respectively can reduce sulfide 35.29%, 60.33%, 76.28%. And the color decrease was 42.28%, 52.28%, 80.62%. The most effective reduction in sulfide and color is at 90 minutes of contact time, with 12 volt electricity voltage, 3 A electric current and 3 cm between electrodes. This electrocoagulation method can be a simple alternative to processing liquid waste with several other considerations. The electricity tariff used in the electrocoagulation process with a oltage of 12 volts, a current of 3 amperes and a time of 90 minutes is: 0.054 kWh × Rp.1,420.12/kWh = Rp.76,14648
