Modeling of by-product recovery and performance evaluation of Electro-Fenton treatment technique to treat poultry wastewater

Due to its low viscosity, soybean oil is commonly used as edible oil. Its production is accompanied by a large amount of wastewater containing hazardous materials like phenolic compounds. In this study, the electro‐Fenton process with response surface methodology was applied for oil removal from wastewater of soybean oil plants. Five independent variables, including reaction time, pH, current density, molar ratio of H2O2 to Fe2+, and volume fraction of H2O2 to wastewater, were investigated for their effects on oil removal. The significant independent variables were optimized by the Box‐Behnken design. The optimum conditions were statistically obtained, and the results were confirmed by experiment. 92.66 % oil removal were experimentally found for the optimum conditions.

“…In recent years, the anaerobic process, especially carried out in the upflow anaerobic sludge blanket (UASB) reactor, is being adopted to treat the wastewater having relatively higher organic pollutants due to its demonstrable performance and cost saving advantage. UASB system has been successfully applied to treat wastewater from vegetable processing industry, distillery, petrochemical industry, etc., [5][6][7][8]. Various treatment methods have been used recently for the treatment of bagasse effluent.…”

Thirugnanasambandham (2015): Response surface modeling and optimization of upflow anaerobic sludge blanket reactor process parameters for the treatment of bagasse based pulp and paper industry wastewater, Desalination and Water Treatment,The interactive effects of influent chemical oxygen demand (COD in ), hydraulic retention time (HRT), and temperature on the performance of an upflow anaerobic sludge blanket reactor, operated in continuous mode, were studied for the anaerobic biodegradation of bagasse effluent from pulp and paper industry. Experiments were conducted based on Box-Behnken design and analyzed using response surface methodology. COD in (4,400-6,800 mg/l), HRT (15-27 h), and temperature (20-40˚C) were the operating variables considered for this study. Three dependent parameters viz., percentage of COD removal, COD removal rate, and biogas production were either directly measured or calculated as response. Analysis of variance showed a high coefficient of determination value (R 2 ) of 0.9990 for percentage COD removal, 0.9960 for COD removal rate, and 0.9953 for biogas production thus ensuring a satisfactory fit of the second-order polynomial regression model with the experimental data. Maximum values of percentage COD removal (84.3%), COD removal rate (230.9 mg/l h), and biogas production (21.2 l/d) were observed at optimum COD in , HRT, and temperature of 6212 mg/l, 23 h, and 35˚C, respectively.

“…In addition, through polymerization, the formed flocs can be removed by sedimentation and floatation [15]. Despite the general applicability of the electrochemical technologies for treating wastewater of different kinds, they have also been increasingly used for the treatment of poultry wastewater [16][17][18] under different electrode combinations, such as using aluminum electrodes [19] as well as iron electrodes [20]. Moreover, the performance of electrodes in a wastewater treatment system can be highly affected by the choice of electrode materials [21], combination [22], as well as the characteristics of the wastewater to be treated.…”

Understanding the efficiency of different wastewater treatment technologies tested under real conditions is essential for successful decision making by engineers and managers. In this study, real poultry slaughterhouse wastewater coming from defeathering, cooling, and evisceration processes was treated using a lab-scale electrochemical process by use of iron-iron (Fe-Fe), iron-graphite (Fe-Gr) and aluminum-graphite (Al-Gr) electrode combinations. A water quality index (WQI) was developed and used as a tool for evaluating and classifying the effectiveness of different electrode combinations. The Al-Gr electrode combination showed an impressive performance achieving an “excellent” status for all of the three studied sources of wastewater with a WQI ranging from 13 to 34. The Fe-Gr electrode combination showed an “excellent” status performance for the wastewater from the cooling process as classified by the WQI and “good water” class for the defeathering and evisceration processes. The lower performance, which was highly affected by the increase in turbidity, was observed for the Fe-Fe electrode combination with a “poor water” status for the wastewater coming from defeathering and cooling processes and “good water” status for evisceration process.
