PRELIMINARY STUDIES ON THE INVESTIGATION OF THE PHYSICOCHEMICAL COMPOSITION AND ECOLOGICAL PROPERTIES OF OIL SLUDGES
Keywords:
oil sludge, physicochemical composition, ecological hazard, centrifugal separation, bioremediation, utilization.Abstract
This article presents an investigation into the physicochemical composition of oil sludges, their ecological hazards, and modern processing technologies. The results provide a scientific basis for safe management and utilization of sludges in Uzbekistan. The study analyzes the compositional fractions, viscosity, dispersity, and toxic components such as PAHs. The efficiency of centrifugal, thermal, chemical, and biological methods is compared. Ecological risk mitigation strategies are developed based on regulatory frameworks and international experience.
