“…Thus the ratio of BOD to COD is often reported as a way to quantify the relative recalcitrance of organic compounds in wastewater (Yeber et al 1999b;Baig and Liechti 2001;Kreetachat et al 2007;Ghaly et al 2011). This value, which is often in a range between about 0.05 and 0.5 for P&P wastewaters, will help to determine what treatment strategy is appropriate.…”

“…For instance, though improved efficiencies and treatment rates often can be achieved with modern reactors designed for biological wastewater treatment, such results from BOD and COD tests will be different if the wastewater sample contains difficult-to-biodegrade oxidizable compounds or toxic materials that inhibit biological activities. Thus the ratio of BOD to COD is often reported as a way to quantify the relative recalcitrance of organic compounds in wastewater (Yeber et al 1999b;Baig and Liechti 2001;Kreetachat et al 2007;Ghaly et al 2011).

“…However, Hermosilla et al (2012a) found such a system to be less effective than photo-Fenton treatment in the case considered. Various authors have shown that such systems can be made even more effective by the addition of hydrogen peroxide Catalkaya and Kargi 2008; Ugurlu and Karaoglu 2009;Ghaly et al 2011;Kumar et al 2011). Botia et al (2012) compared TiO2 and ZnO catalysts in the presence of UV light for the treatment of pulp bleachery wastewater.…”

The pulp and paper (P&P) industry worldwide has achieved substantial progress in treating both process water and wastewater, thus limiting the discharge of pollutants to receiving waters. This review covers a variety of wastewater treatment methods, which provide P&P companies with costeffective ways to limit the release of biological or chemical oxygen demand, toxicity, solids, color, and other indicators of pollutant load. Conventional wastewater treatment systems, often comprising primary clarification followed by activated sludge processes, have been widely implemented in the P&P industry. Higher levels of pollutant removal can be achieved by supplementary treatments, which can include anaerobic biological stages, advanced oxidation processes, bioreactors, and membrane filtration technologies. Improvements in the performance of wastewater treatment operations often can be achieved by effective measurement technologies and by strategic addition of agents including coagulants, flocculants, filter aids, and optimized fungal or bacterial cultures. In addition, P&P mills can implement upstream process changes, including dissolved-air-flotation (DAF) systems, filtration save-alls, and kidney-like operations to purify process waters, thus reducing the load of pollutants and the volume of effluent being discharged to end-of-pipe wastewater treatment plants.

Abstract-The Fenton process is one of the most powerful advanced electrochemical processes based on the production of hydroxyl radicals (OH . ) as a result of the reaction of hydrogen peroxide (H 2 O 2 ) with catalyst ferrous ions (Fe 2+ ) under acidic conditions. In this study, tissue paper wastewater with the initial COD concentration of 1200 mg/L was treated using Electro-Fenton method. The cylindrical iron electrochemical reactor was used as a cathode. The turbine impeller with 8 flat blades were used as an anode. The effects of initial pH, current density and concentration of H 2 O 2 on COD removal efficiency were determined. The removal efficiency of 80 % were obtained after 60 minutes of electro-fenton process at the current density of 20 mA/cm 2 with the addition of 0.1M H 2 O 2. Additionally, the electrical energy consumptions were also evaluated. It can be concluded from the study that reactor designed dissimilar from those in the literature, can be used successfully for COD removal from the tissue paper industry wastewater.Index Terms-Tissue paper wastewater, electro-fenton, wastewater treatment, COD.
