Abstract
Abstract — Lignin wastewater from pulp and paper industry is a hazardous and toxic waste which has to be treated prior to disposal due to high content of recalcitrant organics which lead to high concentration of COD. The wastewater can be treated with Advanced Oxidation Technology (AOT) by using Fenton’s reagent (H2O2 and Fe2+) in batch and isothermal (30°C) condition. The experiments were carried out to evaluate the kinetic and economic aspects for the application of Fenton’s reagent in lignin wastewater degradation. The parameters used in this study were 1) concentration of H2O2, 2) molar ratio of Fe2+/H2O2, and 3) the value of initial wastewater pH. The Fenton process is effective at H2O2 concentration of 0,084 mol/L, Fe2+/H2O2 ratio of 1:20, and pH of 3.0. The results show that the removal of lignin, COD and colour are 100%, 67% and 99% respectively after 120 minutes reaction. The COD degradation kinetic is pseudo first order with the kinetic constant is 0.0113 min-1 and chemical cost for this treatment is estimated to be IDR 350.433/L wastewater.
