| Abstract | A pilot-scale vertical flow constructed
wetland (VFCWs) system was designed, implemented and operated for one year for
the treatment of dye-rich real textile effluent. Brachiaria mutica was
vegetated to develop VFCWs in which five different textile effluent degrading
endophytic bacteria were inoculated. These bacteria were screened based on
their dye degrading and plant growth promoting capabilities. The system's
performance was evaluated by monitoring physicochemical parameters, nutrients
removal, heavy metals reduction, detoxification potential, and persistence of
endophytic bacteria in the plant rhizo- and endosphere. Although VFCWs were
able to remove a majority of the pollutants from the wastewater, bacterial
augmentation further enhanced the remediation efficiency. The system promoted
an increase in dissolved oxygen up to 188% and, concomitantly, a substantial
decrease in the chemical oxygen demand (81%), biochemical oxygen demand (72%),
total dissolved solids (32%), color (74%), nitrogen (84%), phosphorous (79%),
and heavy metals [Cr(97%), Fe(89%), Ni(88%), Cd(72%)] was recorded. Wastewater
treated with VFCWs augmented with bacteria was found to be non-toxic and
inoculated bacteria showed persistence in the root and shoot interior of B.
mutica. Conclusively, VFCWs proved to be an effective methodology for
treatment of textile effluent whereas its smaller size with high efficiency is
an advantage for field-scale applications.
