Treatment of Slaughterhouse Industry Wastewater with Ultrafiltration Membrane and Evaluation with Life Cycle Analysis

Slaughterhouse wastewater is one of the most produced industrial wastewater in the world. This wastewater can cause a high level of pollutant effect when the process is given to riverbeds or sewage systems without any treatment. Wastewater contains proteins, fats, carbohydrates in the treatment of blood, skin and feathers, which results in much higher biological oxygen demand (BOD) and chemical oxygen content (COD) In this study, the use of wastewaters with high organic, nitrogen (N) and phosphorus (P) as an agricultural product has been examined. In addition to these results, the Life Cycle Analysis (LCA) of the ultrafiltration system was also carried out. Accordingly, the effects of ultrafiltration system on human health, ecosystem quality, climate change and resources were calculated as 0,00000046 DALY, 0,134 PDFxm2yr, 0,336 kg CO2 eq and 6,937 MJ respectively. In the light of the results, it is thought that the wastewaters of the slaughterhouse industry can be used as irrigation water after passing through the ultrafiltration membrane because of the high amount of N and P.
