The purpose of this research focused on analyzing how the variation in the volumetric ratio of compost/sawdust and the exposure time affects the removal of Fe (II) and the pH in acidic solutions simulated using an artificial wetland. The methodology addressed physical-chemical aspects, using techniques such as the measurement of Fe (II) concentration by UV-visible spectrophotometry, pH and electrical conductivity. The experimental design had an explanatory, applied and quantitative approach; as well as bifactor type. Considering different volumetric ratios of composting/sawdust (1/2, 1/1, 2/1) and operation times from 12 to 120 hours. Constructed wetlands, each with a specific compost/sawdust ratio, were constructed and operated, and periodic measurements of physicochemical properties were carried out. As a result, it was evident that as the proportion of composting in the volumetric ratio increased, a gradual increase in pH values was observed. This phenomenon is solved with the release of organic acids during the decomposition of the compost, acting as plugging agents that counteract the initial acidity of the compost. Regarding the removal of Fe (II), an increasing trend was noted over time, regardless of the volumetric ratio. This improvement in efficiency was attributed to biological and chemical processes that intensify with the duration of wetland operation. Concluding that, the interaction between these variables proves to have a significant impact, highlighting the importance of considering both the composition of the composting material and the exposure time of water in anaerobic wetlands.
