Treatment of domestic wastewater by potential application of a submerged aquatic plant Hydrilla verticillata Casp

All over the world wastewater pollution is common. Untreated municipal wastewater posing eutrophication, where water is enriched with nutrients and unhygienic to use. Control of eutrophication is burning issues for aquatic sites around the world. In such a state, remediation of nutrients by aquatic plants is remarkable for municipal wastewater treatment. Present study was conducted by off-site experiment, where Hydrilla verticillata Casp was cultured in a tub for subsequent seven days over one year. Second one of the tub was used as control. The quality of domestic wastewater was assessed before and after the experiment by analyzing physicochemical parameters following APHA-AWWA-WPCF-1980. The results of the present experiment revealed the significant improvement in the quality of municipal wastewater, as indicated by the decrease in values  of most physicochemical parameters studied, except pH,  Dissolved oxygen and plant biomass. That showed efficiency and potentiality of aquatic plant for the purpose.
