Contribution of Electrolysis within an Integrated System for a Poultry Slaughterhouse Wastewater Treatment

Abstract

Treatment of poultry slaughterhouse wastewater before disposal or reuse is an essential part of human health and environmental protection in general. This study aimed to investigate the influence of the pre-treatment system based on electrolysis technology within an integrated lab-scale treatment plant in the removal of contaminants from poultry slaughterhouse wastewater. Several treatment units (averaging tank, feather catcher, fat catcher, and coarse mechanical filter) were connected in series before the electrolysis chamber. While in general, the entire integrated system also included some other units such as ultra-filtration, reverse osmosis, and the ultraviolet lamp connected in series. From the analysis results, it was observed that the pre-treatment phase with electrolysis had a significant influence on the general performance of the treatment plant. The pre-treatment contributed to about 33.5% to 100% in the general contaminants’ removal efficiency. The highest contribution was observed from the total chlorine (100%), nitrate (98.2%), as well as BOD (95.3%). The lowest contribution was observed from the nitrite removal, with 33.5%. This study revealed further that the integration of electrolysis technology in a wastewater treatment system has a significant potential for developing an effective wastewater treatment plant.

Polarity Effect of Stainless-Steel and Copper Electrode Materials for the Purification of Slaughterhouse Wastewater

“…The EC treatment methods have been widely used to treat various types of wastewater in the field of wastewater management, including poultry slaughterhouses [15], phenolic wastewater [16], textile dye wastewater [17], Cyanide Wastewater [18], tannery wastewater [19], coal tar wastewater [20], and sugar factory wastewater [21]. General demand for electrochemical wastewater treatment techniques has been rising quickly.…”

The irrigation suitability potential of an effluent treated by a pseudo‐natural wetland

“…For instance, municipal wastewater is reused for irrigation in dry countries because it provides a stable source. Moreover, wastewater management, in general, has been a major global issue of concern for many years (Meiramkulova et al, 2021). Many technologies have been studied for their applicability in wastewater purification, including electrochemical methods (Mkilima, 2022), natural zeolite (Meiramkulova et al, 2022; Mkilima et al, 2021), membrane filtration (Meiramkulova et al, 2020) and constructed wetlands (Hassan et al, 2021).…”
