Assessment of Pathogen Removal Potential of Root Zone Technology from Domestic Wastewater
Journal Title: Universal Journal of Environmental Research and Technology - Year 2013, Vol 3, Issue 3
Abstract
Root zone technology using constructed wetland (CW) for the treatment of domestic waste water was selected for the present study. Selected wetland unit was built during 2000 on the unused soil of Education College receiving the discharge of the sewage from the Ravindra Nagar (residential colony) at Ujjain (230 12’ N latitude, 750 42’E longitude), situated in Madhya Pradesh, India. Results reveal that the mean reduction of indicator bacteria, total coliform and faecal coliform was 96% and 99% respectively in the inlet and outlet waste water from constructed wetland. Average reduction of waterborne bacterial pathogens, Salmonella, Shigella and Vibrio was 94%, 87% and 94% respectively through constructed wetland in three seasons e.g., rainy, winter and summer. Data collected from the experiments were statistically significant over their respective controls. The overall study strongly recommends the use of constructed wetland for treatment of domestic waste water for pathogenic bacteria, besides pollutant. Although it was a preliminary study, but originality of results are quite promising in terms of pathogenic bacterial removal from the wastewater.
