It is generally accepted that industrial wastewater like tannery effluent is high strength wastewater. The aim of this study was to examine the capacity of Vetiver grass for the treatment of high strength wastewater in a constructed wetland. Two constructed wetland beds were designed and one of them was not planted used as a control group. The grass was planted with 20 cm by 20 cm distance from each seedling. The biometric characteristics of Vetiver grass was evaluated by taking randomly selected clusters of the grass. The concentration of chromium in the extract of parts of the grass was determined by atomic absorption spectrophotometer. The Chromium bioaccumulation and Translocation factor was estimated. Composite samples before and after treatment of 4 different hydraulic retention time was collected. The physiochemical analysis of the wastewater has been carried out. The constructed wetland bed with Vetiver grass performed that, BOD, COD, NH4-N, NO3-N, TN, PO4-P, and TP were reduced at the retention time of 9 days by 91.9%, 96.3%, 62%, 86%, 88.7%, 96.3%, and 92.2% respectively. Chromium was also reduced by 97% at retention time of both 7 and 9 days over the planted bed. The bed with plant performs significantly better than without plant at P-value <.01. Therefore, Vetiver grass has a capacity to reclaim high strength industrial wastewater in tropical areas.

Abstract Liquid effluent produced from tanning industries is loaded with organic and inorganic contaminants, particularly heavy metals, which may cause severe damage to the ecosystem. Constructed wetland (CW) is a promising product of the research in the field of ecological engineering which helps to overcome aquatic pollution. This investigation aims to develop a plant–endophyte synergism in CW for the efficient remediation of tannery effluent. In a vertical flow CW, Brachiaria mutica was vegetated and augmented with three endophytic bacterial strains. Results showed a reduction of 82% in COD, 94% in BOD5, and 95% in Cr by plant–endophyte synergism in CWs and it was significantly higher than the use of plants alone. Similarly, nutrients (N and P), lipids, ion content, SO42−, and Cl− showed similar reduction by the combined action of endophytes and B. mutica in CWs. The endophytes inoculation enhanced bacterial population in different compartments of the plants vegetated in CWs and the maximum was observed in the roots. This study revealed that plant–endophyte synergism in CWs can enhance the remediation of industrial wastewater.

Abstract The performance of an integrated wastewater treatment system composed of horizontal subsurface flow constructed wetland (HSSFCW), floating constructed wetland (FCW), and anaerobic baffled reactor (ABR) was studied for pollutant removal from seed production wastewater. Cyperus alternifolius (Umbrella Papyrus) plants were used in the HSSFCW, and Vetiveria zizanioides (Vetiver grass) in the FCW. The ABR was fed with 25 m3/d wastewater from its equalization tank. The average raw wastewater organic loading rate was 0.208 kg-COD/d. Grab wastewater samples were collected twice weekly for three months from each unit's inlet and outlet. The system's performance in removing biochemical oxygen demand (BOD5), chemical oxygen demand (COD), total suspended solids (TSS), turbidity, nitrate, phosphate, and ammonium was studied. The average removal efficiencies obtained were 95.5% BOD5, 94.6% COD, 86.2% TSS, 76.6% turbidity, 82.4% nitrate, 76% phosphate, and 32.9% ammonium. The results show that integrating ABR, HSSFCW, and FCW improves pollutant removal from seed production wastewater, and the treated water can be used for agricultural purposes.
