Constructed wetlands are established efficient technologies and provide sustainable solution for wastewater treatment. SimilarlyBiochar, which is an organic material, produced by means of pyrolysis, offers simple and low cost techniques to treat water and reduce carbon footprint. Combining both of these technologies can greatly augment the efficiency of the system. The objective of this study was to evaluate the efficiency of constructed wetlands by combining it with biochar. Horizontal wetland beds were prepared using gravels, biochar and cultivatedwith Cannaspecies. These beds were saturated with wastewater with a retention time of 5 days. Performance parameters were assessed by estimating reduction of COD, TN, NH3, NO3-N, TP, PO4-P between controlled and experimental wetland beds. The study revealed that wetland with biochar was more efficient as compared to wetland with gravels alone. |
