Waste Water Treatment by Using Reed Bed System

Abstract

The waste water generated from the boys hostel and girls hostel SIT campus were collected andanalyzed. Conventional treatment method and the method of purification using Reed bed for the treatment of effluent were compared. The plant used for this purpose was Setaria italica and ornamental plant which is locally known as Foxtail millet (Thinai) and Flax lily. The experiment was conducted with the Primary treated sewage taken from the Sewage Treatment Plant (SIT STP) of our campus. From the experiment it is found that the one with Reed Bed system givesa better quality treated water vis-à-vis the campus STP treated water. Hence, the filter bed of SIT STP is planted with Setaria italica and ornamental plant as a trial run. The project presents the method of construction of root zone bed and the effectiveness of removal of various contaminants using this root zone treatment process. The results for raw water and treated water samples were compared and discussed
