Abstract

With the interest to reuse and recycle the wastewater for technological use, this project aims to test the treatment of wastewater from poultry slaughterhouse industry from three main sections of the poultry slaughtering process, defeathering, eviscerating and cooling processes. The samples for the project were obtained from Izhevskoe a Kazakhstani company. The technology used is a combination of electrocoagulation, ultrafiltration, and photochemical system and its goal is to provide treated water that can be re-utilized in the poultry industry for sterilization of technical equipment without contaminating and affecting the quality of the poultry products. The treatment of wastewater samples lasted in total for 40 min. From the results, it was found that indicators such as BOD, COD, and phosphates had removal efficiency of almost 100%, while the microbiological colonies were all eradicated from then wastewater making the treated water microbes free. Hence, proving this system to be effective for the treatment of poultry slaughterhouse wastewater and safe for technological reutilization.

Highlights

With the interest in reusing and recycling the wastewater, scientists from across the globe are finding adequate and efficient treatment for poultry slaughterhouse wastewater
The results obtained (Table 2) from the analysis proved to be impressive as the pollutant level of most indicators in the wastewater decreased by more than 90%
Other studies proved that the initial decrease in pH value during the EC process is beneficial for the pollutant removal, improving the overall removal efficiency

Summary

Introduction

With the interest in reusing and recycling the wastewater, scientists from across the globe are finding adequate and efficient treatment for poultry slaughterhouse wastewater. Electrocoagulation (EC), ultrafiltration, and photochemical treatment are only some to in the list that are possible methods that could be employed to treat the effluent from the poultry slaughterhouse industry and other industries (Meiramkulova et al, 2018c). There have been several studies on the effectiveness of wastewater treatment using the EC process that proved it to be effective (Bayramoglu et al, 2004; Kobya et al, 2003; Can et al, 2003; Lin and Chen, 1997; Meiramkulova et al, 2018a). Cathode and solution can be observed from the following reaction (Picard et al, 2000): Anode: Ms → Manq+ + ne− Cathode: 2H2O + 2e− → 2OH− + H2 Solution: Manq+ + nOH− → M(complex) → M(OH)n(s)
