Abstract

This study investigated an integrated treatment system combining coagulation, adsorption, filtration, and ceramic membrane processes for songket dyeing wastewater. Textile wastewater is characterized by high color intensity, suspended solids, and organic loads, which can cause serious environmental impacts if discharged without adequate treatment. Coagulation using aluminum sulfate effectively destabilizes colloidal particles, followed by adsorption with activated carbon to remove dissolved dyes and organic compounds. Multimedia filtration and ceramic membrane filtration further enhance pollutant removal through physical separation mechanisms. The integrated system successfully achieved color reduction from 976.5 Pt-Co to 10.6 Pt-Co, TSS reduction exceeding 98%, and COD reduction above 93%, in accordance with Indonesian wastewater discharge standards for the textile industry (KLHK, 2016).Keywords: Songket Wastewater, Coagulation, Adsorption, Filtration, Ceramic Membrane

Abstract

The aim of this research is to determine the effect of bentonite-Titanium dioxide (Benonite-TiO2) composite on the degradation process of methylene blue. It was carried out by synthesizing the composite through the impregnation of Titanium dioxide (TiO2) on bentonite and then characterizing the obtained compound using XRD and SEM-EDX. The results of the XRD characterization showed that there was a shift in the diffraction angle (2θ), which indicated the success of the impregnation procedure. The morphology of the composite showed that the bentonite surface had been filled with TiO2, as evidenced by the results of the EDX analysis, which showed a 7.03% increase in Titanium. Furthermore, the degradation process was carried out using various variables, including contact time, the ratio of composite weight to dye, and by irradiation with a UV lamp at a wavelength of 352 nm UV. It was discovered that the best degradation in the concentration of methylene blue occurred at a maximum contact time of 90 minutes and at a maximum weight of 10 mg of benonite-TiO2, with an effectiveness of 99.91% after irradiation and 92.26% without irradiation.
