Metagenomic Tool Based Wastewater Treatment Technology

The organic molecules are treated depending on their nature in a suitable environment. Metagenomic tool is based on the concept that the microbes in an in-situ condition behave under a stressed condition which is not necessarily ideal. The treatment system consists of Bio reactor (Meander type septic tank) followed by a 50 Sq-m of constructed wetland. The bed has wetland plants growing over the gravel media and is designed as a horizontal sub-surface flow (HSSF) wetland system. The bed is rectangular in shape with gravel layer up to 0.8 m deep. The filter bed is comprised of coco powder, river pebbles, stones and gravels as filter media and Vetiver as wetland plants. The inlet and outlet zones are filled up with larger gravels of 50-100mm diameter. A water regulation chamber is present before the final collection tank. The septic tank provides solid retention time with quiescence in which microbial degradation and pathogen elimination occurs. The effluent from the septic tank overflows to the HSSF. The wetland plants along with the filter media help in the further degradation and pathogen removal in the wastewater.
