Evaluation of Electrochemical Methods for Poultry Slaughterhouse Wastewater Treatment

Abstract

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.

Efficacy Advanced Chemical Oxidation Process (AOP) for Sustainable Pretreatment of Mixed Dairy and Poultry Wastewaters in Nablus, Palestine

“…They underlined the role of AOP with coagulation and flocculation as a cost-competitive option for the pretreatment of industrial wastewaters. Advanced oxidation process is not a new technology, Peres et al [18] listed other advanced technologies including electrochemical [19], and membrane-based processes,…”

Performance of a Combined Treatment Approach on Elimination of Microbes from Poultry Slaughterhouse Wastewater

“…In addition to chemical disinfectants, ultraviolet (UV) radiation has also been used for many years as a water disinfection technology in the field of wastewater treatment [14]. Also, some other advanced approaches such as ozonation and membrane filtration [15] as well as electrochemical (EC) methods [16] have been applied to poultry slaughterhouse wastewater treatment. But, the performance of the treatment technologies has also been observed to be affected by the scale and characteristics of wastewater subjected to the treatment process [17].…”

Performance of an Integrated Membrane Process with Electrochemical Pre-Treatment on Poultry Slaughterhouse Wastewater Purification

“…Because of the potential risks posed by such highly polluted wastewater to human health and the environment in general, the treatment of poultry production wastewater before discharge or reuse has been of major concern [ 5 ]. Moreover, the technical and economic feasibility of a poultry production wastewater treatment is highly dependent on the technology used [ 6 , 7 , 8 ]; which also includes the scale at which the particular treatment system is operating [ 9 ]. Therefore, having a clear knowledge of a treatment technology ability before its application for poultry wastewater treatment is of significant necessity; which in turn brings the importance of conducting research.…”
