Abstract
This article is dedicated to the theoretical and practical issues of increasing the efficiency of advanced treatment and reuse technology for complex wastewater and industrial water in oil and gas enterprises. The study highlights the scientific-methodological and physicochemical patterns of a hybrid treatment system based on hydrodynamic flocculation, modified granular filtration, and nanostructured polymer membranes. Experiments were carried out in the operational conditions of oil and gas facilities, achieving a high degree of technical water purification from petroleum products, reduction of suspended solids, and a decrease in total salinity. The mechanisms of membrane bio-fouling and scaling were modeled using the Kedem-Katchalsky and Ergun equations. The developed technology enables the creation of a closed-loop water supply cycle in oil and gas enterprises and reduces fresh water consumption.
