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.
