Abstract

 IN THE RECENT YEARS, PULP AND PAPER RECYCLING INDUSTRIES HAS BEEN DEVELOPED. BECAUSE OF CONSUMPTION HUGE AMOUNTS OF WATER, THESE INDUSTRIES PRODUCE A LOT OF WASTEWATER. RECYCLING PAPER ORGANIC NATURE OF WASTEWATER CONTAINS A LOTS OF LIGININED AND CHLORINATED COMPOUNDS RECALCITRANT TO BIOLOGICAL TREATMENT. ADVANCED ELECTROCHEMICAL OXIDATION PROCCESSES BY USING FENTON ARE ENVIROMENTALLY FRIENDLY THAT ATTENTION TO THE WATER TREATMENT METHOD IN THE RECENT YEARS. AMONG THE ADVANCED ELECTROCHEMICAL OXIDATION PROCCESSES, ELECTRO FENTON METHOD IS MORE ATTENTIONED. IN THIS STUDY, ELECTRO-FENTON METHOD USING SIX IRON ELECTRODES ARRANGED IN MONO-POLAR MODE, PARALLEL CONFIGURATION HAS BEEN INVESTIGATED FOR TREATMENT OF PAPER RECYCLING WASTEWATER. THE EXPERIMENTS HAVE BEEN CONDUCTED ACCORDING TO DESIGN OF EXPERIMENTS DONE BY RESPONSE SURFACE METHODOLOGY (RSM) USING BOX-BEHNKEN DESIGN. DURING THE INVESTIGATION, EFFECTS OF THE OPERATING PARAMETERS SUCH AS CURRENT DENSITY, CONCENTRATION OF HYDROGEN PROXIDE, AND TREATMENT TIME HAVE BEEN STUDIED ON THE COLOR REMOVAL EFFICIENCY. IN OPTIMUM CONDITIONS, CURRENT DENSITY, CONCENTRATION OF HYDROGEN PROXIDE, AND TREATMENT TIME WERE 75 A/M2, 0.00912 MOL/L AND 70 MIN, RESPECTIVELY. UNDER THE MENTIONED CONDITIONS, WHEN ALL HYDROGEN PROXIDE ADDED AT FIRST, THE COLOR REMOVAL EFFICIENCY, TURBIDITY REMOVAL EFFICIENCY, COD REMOVAL EFFICIENCY, AND ENERGY CONSUMPTION WERE OBTAINED 96.46 %, 89.59 %, 78.01 % AND 2.77 KWH/ (KG OF REMOVED COD), RESPECTIVELY.
