Abstract

This paper examines the environmental implications of industrial wastewater generated by food processing enterprises in Uzbekistan and proposes an integrated wastewater management system aligned with national environmental standards. The study evaluates pollutant loads, treatment efficiency, and the ecological risk of untreated discharge into Uzbekistan's water bodies. A multi-stage treatment scheme is developed and validated, demonstrating significant reductions in key contaminants and full compliance with O'zDSt 950:2011 and the National Water Law No. 837-II.
