Removal of Textile Dye by using Eichhornia spp. and Pistia spp. by Aquatic Macrophytes Treatment Systems (AMTS) ? An Eco Friendly Technique

Dyes are extensively used in various branches of the textile industry, leather industries, paper production, food technology and agriculture research. The dye effluents of these industries produces pollution when they are discharged in natural resources like underground stream, rivers, ponds and lakes which are the drinking water sources without any treatment. This causes serious problems of health in whole population. Textile dye effluent contains substantial pollution load which increases the change of physicochemical parameters. So pre-treatment is needed prior to discharge of these effluents. In the present study, an attempt is made to compare the efficiency of aquatic macrophytes like Eichhornia crassipes and Pistia stratiotes to treat the dye effluents. Water was initially analyzed for physicochemical parameters i.e. pH, TS, DO, COD and dye concentration. After 07 days, of phytoremediation same physical and chemical parameters will be measured.There was statistical significant decrease in COD of dye effluents with different interval of days. In general, all the effluent samples collected were devoid of DO. There was increase in the DO after treatment as indicated by reduction of COD in the effluents. The results indicate that the water hyacinth is very efficient in reducing the pollution loads in dye effluents.At the present time AMTS, a phytoremediation is still a nascent technology that seeks to exploit the metabolic capabilities and growth habits of aquatic macrophytes: delivering a cheap, soft and safe biological treatment that is applicable to specific contaminated sites and wastewaters is a relatively recent focus. In such a context, there is still a significant need to pursue both fundamental and applied research to provide low-cost, low-impact, visually benign an eco friendly technique. AMTS includes its tolerance to dye and dye absorption along with good root development, low maintenance and ready availability in contaminated regions.Colour reduction of effluent water was prominent Eichhornia crassipes proves to be an effective aquatic plant in reducing the pollution load of the effluent waters.
