ROLE OF AQUATIC PLANTS IN TREATING WASTEWATER - A SUSTAINABLE APPROACHS. PACKIALAKSHMI, T.K. PADMINI, G. SHAKILA AND V. PRIYANKAAbstract In India, the water shortage is one of the major concerns as the demand for water is increasing withthe constrained supply sources. It necessitates the research on waste water reusal techniquesparticularly on grey water treatment options which plays the vital role in the aspect of sustainable water management. Improper waste water management creates the environmental threats and fataldiseases. The present study analyzed the simple sand filter bed method of treatment and the sandfilter with reed beds and is compared for successful waste water management. The aquatic plantused for this purpose was Phragmitisaustraliswhich is locally known as NANAL. The model greywater is tested for the different loading condition and retention period using root zone treatmentprocess. The study concludes that system of reed bed is more efficient than conventional sand bedfiltration methods by analyzing the various physio chemical and biological parameters.
