Abstract

The efficiency of a wastewater treatment process may be affected by several factors including the scale at which the system is operating. This study aimed at investigating the influence of scale on a poultry slaughterhouse wastewater treatment process. The process is comprised of several units including electrolysis, membrane filtration, and ultraviolet irradiation. The results of the industrial-scale wastewater treatment plant of the Izevski poultry farm slaughterhouse in Kazakhstan were compared with those of a lab-scale wastewater treatment process under the same conditions. The traditional and water quality index (WQI) approaches were used to present the results and the drinking water quality standards of Kazakhstan were used as a reference. The industrial and lab-scale plants showed high purification efficiency for most of the studied water quality parameters. The comparative analysis based on the WQI showed that the industrial-scale wastewater treatment plant outperforms the lab-scale wastewater treatment process.

Highlights

The poultry industry is recognized as one of the largest and rapidly growing agro-based sectors around the world
The wastewater generated from a poultry industry contains large amounts of proteins, fats, and carbohydrates resulting from meat, blood, skin, and feathers, which in turn lead to high biological oxygen demand (BOD) and chemical oxygen demand (COD)
The industrial-scale treatment plant achieved an efficiency of 100% for color, total suspended solids (TSS), and free chlorine, and most of the other parameters were successfully purified with the range of efficiency from 99 to 100%

Summary

Introduction

The poultry industry is recognized as one of the largest and rapidly growing agro-based sectors around the world. This is attributed to the increasing demand for poultry meat and egg products due to urbanization, population rise, and income increases [1]. The poultry industry is facing many challenges including the large amounts of waste produced, which accumulate and may pose disposal and pollution problems unless sustainable management methods are implemented [2]. The wastewater generated from a poultry industry contains large amounts of proteins, fats, and carbohydrates resulting from meat, blood, skin, and feathers, which in turn lead to high biological oxygen demand (BOD) and chemical oxygen demand (COD). Wastewater from a poultry production process is considered to be polluted water, making it unsuitable for certain uses such as drinking, irrigation, or swimming [4]
