Impact of Planting Density on the Effectiveness of Laboratory-Scale Artificial Wetlands Planted with Limonium Perezzi for Tannery Wastewater Treatment
The impact of the planting density of Limonium perezzi on the effectiveness of laboratory-scale artificial wetlands for the soaking stage wastewater treatment in tanneries was analyzed. The planting densities were 10.27 plants/m2 (HAP4) and 15.4 plants/m2 (HAP6). The hydraulic retention time in each...

| description | The impact of the planting density of Limonium perezzi on the effectiveness of laboratory-scale artificial wetlands for the soaking stage wastewater treatment in tanneries was analyzed. The planting densities were 10.27 plants/m2 (HAP4) and 15.4 plants/m2 (HAP6). The hydraulic retention time in each wetland was 4.5 days, and the experiments were conducted for 32 days, when the plants began to wither and water samples were taken for the respective analysis. The wetlands were operated for 8 weeks to observe their deterioration with respect to time. The stabilization period of the wetlands varied between 7 and 10 days until the concentration of the effluent was little variable. The statistical analysis of the results indicates that the planting density influences the effectiveness of the wetland in terms of percentage of concentration decrease, the wetlands planted with 15.4 plants/m2 were more efficient, which was determined with the Student’s T test (p<0.05). The percentages of decrease in the chemical demand for oxygen, chlorides, and Total Dissolved Solids (TDS) for the highest planting density were 81%, 54%, and 55%, respectively. As in previous studies, it was observed that the planted species has the ability to absorb salt and release it through leaves and stems, as observed from the seventh day of operation. |

Se analizó el efecto de la densidad de plantación de la especie Limonium perezzi sobre la efectividad de humedales artificiales a escala de laboratorio para el tratamiento de aguas residuales de la etapa de remojo en curtiembres. La densidad de plantación fue de 10.27 plantas/m2 (HAP4) y 15.4 plantas/m2 (HAP6), el tiempo de retención hidráulica en cada humedal fue de 4.5 días y los experimentos fueron realizados por 32 días, tiempo en el que las plantas comenzaron a marchitarse, dentro de los cuales fueron tomadas muestras de agua para el respectivo análisis. Los humedales fueron operados por 8 semanas a fin de observar el deterioro de estas con respecto al tiempo. El periodo de estabilización de los humedales varió entre 7 y 10 días hasta que la concentración del efluente fue poco variable. El análisis estadístico de los resultados indica que la densidad de plantación influye sobre la efectividad del humedal en términos de porcentaje de disminución de concentración, los humedales plantados con 15.4 plantas/m2 fueron más eficientes, lo cual se determinó a partir de la prueba T de Student (p < 0.05). Los porcentajes de disminución de la demanda química de oxígeno, cloruros y sólidos disueltos totales para la mayor densidad de plantación fueron de 81 %, 54 % y 55 % respectivamente. Al igual que en estudios previos, se observó que la especie plantada tiene la habilidad de tomar sal y liberarla a través de hojas y tallos, hecho que se pudo apreciar a partir del séptimo día de operación.
