Abstract
Batik wastewater contains high concentrations of organic and inorganic pollutants such as TSS, COD, and colorants, which can significantly reduce environmental quality if not properly treated. This study aims to evaluate the effectiveness of electrocoagulation and ozonation processes in reducing TSS, COD, and colour in batik wastewater, as well as to analyse the influence of electric current and contact time variations in electrocoagulation and time variations in ozonation. The research was carried out in two stages. First, the electrocoagulation process was performed using aluminium electrodes with variations of electric current (1, 2, 3, 4, dan 5 amperes) and contact times (25, 30, 40, 50, dan 60 minutes). Second, the ozonation process was conducted with contact time variations of (0, 15, 30, 45, dan 60 minutes. The analysed parameters were TSS, COD, and colour, with data further evaluated using ANOVA to determine the statistical significance of treatment factors. The combination of electrocoagulation and ozonation demonstrates significant potential as an alternative method for reducing the pollutant load in batik wastewater, particularly in lowering Total Suspended Solids (TSS), Chemical Oxygen Demand (COD), and color. In the electrocoagulation process, a substantial TSS reduction of 98% and a COD reduction of 67% were achieved. Subsequently, the ozonation process further enhanced the treatment efficiency, resulting in an impressive COD reduction of up to 93% and a color reduction of 37%. These promising results highlight the combined method's capability to support more environmentally friendly wastewater treatment efforts. Keywords: electrocoagulation, ozonation, TSS, COD, colour, batik wastewater.
