Abstract: The Reed bed system with five different native reed plants namely Colocasia esculenta, Xanthosoma sagittifolium, Canna indica, Saccharum spontaneum and Typha domingensis was constructed for the treatment of effluent from the wastepaper based paper and board industry. Screening was carried based on the plant biomass, plant height, shoot length and root length. The effectiveness of the five different reed plants were studied and compared for the removal of Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) in effluent with 7 days of retention time. The best TSS and TDS removal was expressed by the reeds, Colocasia esculenta followed by Typha domingensis and Canna indica. The highest effluent treatment in terms of BOD and COD removal was observed in Typha domingensis and Canna indica respectively. Significant removal of TSS, TDS, BOD and COD was exhibited by Colocasia esculenta, Typha domingensis and Canna indica. The pollutant removal was also positively related to Radial Oxygen Loss (ROL) and the microbial population in the rhizosphere of reed plants. The highest ROL and the microbial population was recorded by the rhizosphere of Colocasia esculenta followed by Canna indica and Typha domingensis. Hence, the reed bed system with the Colocasia esculenta, Typha domingensis and Canna indica can be used as the best biological treatment option for the wastepaper based paper and board mill effluents.
