Resumen

The use of aquatic plants in wastewater treatment processes has been widely implemented in the XXI century given the plant's ability to reduce nitrogen and phosphorus levels in water. This paper studies the convective drying mechanism of green water lentil from an artificial wetland in UDLAP wastewater treatment system. The Taguchi methodology and variance analysis were used to analyze the variation of humidity with time to determine the most effective conditions for convective drying of green water lentil within the experiment design. The results of the experimental convective drying kinetics process suggest that the behavior of absolute humidity in time of the convective drying process of green water lentil can be modelled with a second-grade polynomial. The effective moisture diffusivity coefficients were determined as 2.84E-05cm²/s for a 1000W resistance, 3.685cm²/s for a 2000W resistance, and 5.427cm²/s for a 4000W resistance for the convective drying process. Furthermore, these results are supported by convective drying models found in the literature for lentil drying under similar conditions. The results of this work might serve as the foundation for a potential energy analysis of green water lentil that allows the development of methods to minimize the impact of waste generated from wastewater treatment processes.
