Water is the vital source to live and the textile dye effluent is one of the major contaminants present in the wastewater which is highly toxic to all form of lives. Though some effective various methods such as physical, chemical, and biological methods are available to remove the textile dye effluents, phytoremediation is the most economical, eco-friendly, easy to do to degrade the contaminates completely/partially present in effluent. The different plants are found with naturally inhabited metabolic pathways to utilize different dyes and some of the genetically engineered plants are also produced in order to effectively degrade the dyes and to sustain different environmental conditions. Symbiotic relationships between the plant and microbes are also used to help the plants to overcome different kinds of stress. The enzymes like oxidoreductases which are extracted from the plants have shown potent activity against dyes. The significant decrease in color, turbidity, conductivity, total suspended solids (TSS), total dissolved solids (TDS), chemical oxygen demand (COD), and biological oxygen demand (BOD) are taken as indicators of effectiveness of phytoremediation. Several researchers have done extensive studies in phytoremediation area in order to understand the exact mechanism to during treatment of effluents. This chapter mainly focusses on various phytoremediatic methods and its mechanism used in textile effluents treatments.
