The environmental impacts of wastewater discharge constitute a significant problem, particularly in the paper recycling sector. In this context, the pollution potential of wastewater obtained through centrifugation was examined by performing solid-liquid phase separation. In the study, wastewater obtained in a laboratory environment during the recycling of waste egg cartons was subjected to centrifugation at different operating speeds (1000 RPM and 3000 RPM) and durations (1-10 minutes). Water quality parameters such as pH, electrical conductivity, total dissolved solids, suspended solids, chemical oxygen demand, turbidity, oxidation-reduction potential, and dissolved oxygen were analyzed. In addition, analytical methods such as Fourier Transform Infrared (FT-IR) spectroscopy and UV-Vis spectrophotometry were used to evaluate the comprehensive impact of wastewater. When the experimental findings were examined, it was observed that as a result of separating the wastewater by centrifugation, the COD value decreased from 580 mg/L to 265 and 247 mg/L, the Suspended Solids (SS) value from 236 mg/L to 46 and 27 mg/L, and the turbidity value from 52 NTU to 17 and 9 NTU in the control samples. There was no significant change in pH values of 6.5-7.1 and 6.3-6.7. The results obtained were statistically evaluated and correlation analysis was performed. These results showed that the centrifugation process separated suspended solids in wastewater in phases and physically affected turbidity. It was understood that at higher centrifugation speeds (3000 RPM), more phase separation occurred and more stable performance was achieved compared to the processes carried out at 1000 RPM. In conclusion, the study showed that the centrifugation method for phase separation of wastewater obtained during paper recycling at various durations and speeds facilitated the determination of physical pollution parameters.}, number={1}, organization={TÜBİTAK}
