This study investigates and models the impact of momentum transfer in Deoxygenation for Sustainable Marine Management and Pollution Control in Natural Gas Wastewater Treatment, on the concentrations of dissolved oxygen (DO) and biochemical oxygen demand (BOD) within produced natural gas wastewater in a pond treatment system, particularly under conditions of high precipitation. A comprehensive mathematical model was crafted to quantify the effects of momentum transfer on DO and BOD levels. The fluctuations in BOD and DO concentrations were linked to the influences of momentum transfer, leading to the development and simulation of a mathematical framework that elucidates the role of momentum transfer in the bioremediation of wastewater. The separation of variables technique was employed to derive the general solution associated with momentum transfer. This general solution was subsequently correlated with the specifically developed models for BOD and DO to yield a final equation, which was then simulated across various parameters. The findings from this theoretical model were rigorously compared with empirical data, demonstrating a strong correlation that underscores the utility of the developed model in both monitoring and forecasting the implications of momentum transfer on BOD and DO concentrations. This is particularly relevant for continuous discharges of produced natural gas wastewater into pond systems under high precipitation scenarios. The results highlight the critical function of momentum transfer in enhancing the efficiency of wastewater treatment processes, especially concerning regular effluent discharges stemming from natural gas production operations. This research offers a valuable analytical framework aimed at optimizing wastewater management practices in regions experiencing significant rainfall, thereby promoting sustainable environmental practices in the natural gas sector.
