Penentuan Kondisi Optimum pada Proses Fenton dalam Pengolahan Limbah Tekstil

Abstract

Textile waste from the textile industry activity increases with the textile industry activities. Textile waste has relatively high biochemical oxygen demand (BOD), color, total suspended solids (TSS), electrical conductivity, and zinc content. Therefore, waste treatment is needed. One of the waste treatments is Fenton process using Fenton reagent that is hydrogen peroxide (H2O2) and ferrous sulfate (FeSO4). Fenton reagent can oxidize and degrade organic compounds. In this study, textile waste was tested based on the influence of pH, concentration of hydrogen peroxide, and the concentration of ferrous sulfate. The largest decrease occurred in the BOD under pH 5 in combination with H2O2 concentration of 25 mg/L and the concentration of FeSO4 50 mg/L. Beside that, this combination showed significant reduction of the three other parameters, namely TSS, electrical conductivity, and zinc content.
