SUSTAINABILITY OF CONSTRUCTED WETLANDS IN USING BIOCHAR FOR TREATING WASTEWATER
Constructed wetland (CW) is a reliable, cost effective and sustainable technology for the treatment of different sorts of wastewater via different treatment processes including biological, chemical and physical processes. Coconut Shell (CS) as Biochar was obtained through decomposition of organic material without oxygen. It offers simple, cost effective strategies to treat wastewater and decrease carbon footprint. Consolidation of both (Constructed wetland and Biochar) technologies was adopted to increase the productivity in the treatment of domestic wastewater. Reduction of parameters like nitrogen, pH, turbidity other physicochemical parameters from wastewater using biochar from coconut shell was investigated by mixing the biochar with the wetland soil. Further, in this study analyzed the effect of biochar on the growth of the plants in the wetland(Typha latifolia). The biochar amended wetlands showed greater removal efficiencies of 99.9% and 85% in turbidity and TDS, respectively as compared to the normal wetlands which exhibited an efficiency of 98% and 77.7% in removing turbidity and TDS, respectively.
