ARTIFICIAL CONSTRUCTED WETLANDS A NOVEL IDEA FOR WASTEWATER TREATMENT TO ATTAIN SUSTAINABLE ENVIRONMENT

Abstract

Quality of waste water. Treatment of domestic wastewater from both rural and urban areas pose to be one of the greatest challenges that the government and municipal body incur, in terms of machinery and expenditure. An alternate solution to a cleaner, greener and cost effective method for wastewater treatment is by using a constructed wetland technique. Wetland plants were grown in the lab scale wetland units. The treatment of domestic wastewater was carried out with different detention time periods such as 24 hrs, 48 hrs, and 72 hrs using Phragmites as vegetation with MBBR (Moving Bed Biofilm Reactor) as a part of treatment cell filter media for the lab scale wetland unit. The wetland units developed, consisted of a PVC tub of 70 × 40 × 30 cm and the system was built with a slight slope (<1%) between inlet and outlet zones. The treatment efficiency of the constructed wetland was observed for various parameters like Biological oxygen demand (BOD), Chemical Oxygen Demand (COD), Total Nitrogen (TN) and Total Phosphate (TP). The performance was monitored with different trials and in all the trials the reduction efficiency was found to be more effective. This kind of green initiative of eco-friendly wastewater treatment is found to be future alternative in developing countries and also it is quite economical if the land cost is less in the rural areas.
