LIFE CYCLE ASSESSMENT OF WASTEWATER FROM DAIRY INDUSTRY

In this study, life cycle assessment (LCA) was used to investigated the environmental impacts associated with dairy wastewater treatment. The composition of dairy wastewater was investigated by applying various water quality methods. Indicators like pH, suspension, chemical oxygen demand (COD), bioc...

Indicators like pH, suspension, chemical oxygen demand (COD), biochemical oxygen demand (BOD), extractable substances, detergents, sulfates (SO42-), nitrates (NO3-), nitrites (NO2-), N, P and others were determined.
