DOMINGUES-MARTINEZ, Leyanis et al. Assessment of dye removal with subsurface wetlands. Rev Cub Quim [online]. 2019, vol.31, n.1, pp.108-119. ISSN 2224-5421.

In the present research the dye removal in an experimental subsurface wetland was evaluated. First, the calibration curve of the methylene blue was obtained to evaluate the behavior of the removal of this dye in the wetland, obtaining high removal efficiencies of dye and effluent concentrations below the detection limit of the method. Subsequently, the characterization of the effluent wastewater of "Juan Pedro Carbó Serviá" Factory belonging to the Company of “Confecciones Fénix” was carried out, obtaining that these wastewater does not conform to the Cuban regulation standards for the values of pH and Chemical Oxygen Demand. Finally, the purification of this wastewater in the experimental wetland was evaluated, where an effluent conforms to the Cuban standard of discharge and removal efficiencies of more than 90 % were obtained.
