Phytoremediation of Dye Effluents Using Aquatic Plants: A Study on Eichhornia and Pistia Species

Abstract Synthetic dyes are extensively used in various branches of the textile industry, leather industries, paper production, food technology& agriculture research. The effluents of these industries produces verity of pollution in in nearby sewers & rivers. The remediation of dye effluent after twenty days under the influence of Eichhornia & Pistia species shows the significant change in the concentration of impurities. The change is observed by the analysis of Physico-chemical parameters, Nutrients, Microbial Factors & Solid parameters of treated & untreated dye effluents with different interval of days. The concentration of sodium gives amazing results in both plants for dye effluents. The plants are analyzed for percentage of NPK, which shows significant results for Eichhornia species. The percentage of nutrients absorbed by Eichhornia species shows better results than Pistia species. The degradation of dye effluents by using two ways affects on the concentration of all impurities. It is recognized as one of the root cause of environmental pollution. High concentrations of textile days in water bodies stop the reoxygenation capacity of the receiving water and cut-off sunlight, thereby upsetting biological activity in aquatic life and also the photosynthesis process of aquatic plants or algae
