Abstract
Groundwater is one of the primary sources of clean water widely used by communities; however, it often contains excessive concentrations of iron (Fe) and manganese (Mn) that exceed water quality standards, requiring treatment before use. This study aimed to analyze real-time oxygen transfer characteristics in a continuous Airlift Reactor (ALR) based on the oxygen mass transfer coefficient (KLa) and reaction kinetics for the removal of Fe and Mn using different fine bubble diffuser diameters. The experimental system consisted of a continuous ALR equipped with an Arduino Uno, dissolved oxygen (DO), temperature, water flow, and air flow sensors for real-time monitoring. Fine bubble diffuser diameters of 6, 8, 10, and 12 cm were evaluated under aeration times of 10, 15, 20, 25, and 30 minutes. The results showed that increasing the aeration time increased the dissolved oxygen concentration while decreasing the concentrations of Fe and Mn for all diffuser variations. The 8 cm diffuser achieved the best performance, producing a maximum DO concentration of 6.5 mg/L, Fe removal efficiency of 90.69%, Mn removal efficiency of 79.51%, and the highest KLa value of 0.0321 min⁻¹. Reaction kinetics analysis indicated that Fe removal followed a reaction order of 2.3 with the highest reaction rate constant of 1.644, whereas Mn removal followed a reaction order of 1.7 with the highest reaction rate constant of 0.142 using the 8 cm diffuser. These findings demonstrate that the 8 cm diffuser provides the optimum operating condition for enhancing oxygen transfer while accelerating the oxidation and removal of iron and manganese from groundwater. Keywords: Airlift Reactor, Oxygen Transfer, Reaction Kinetics, Iron, Manganese
