Removal of Dyes and Color from Textile Waste Water by Using Electro Fenton Process

Dye is colored substance has an affinity to substrate to which it is being applied. Dyes appear to be colored because they absorb some wavelengths of light more than others. The presence of dye materials greatly influences the quality of water and the removal of this kind of pollutant is of prime importance. Dyes (Textile) are among the most industrial that release colored wastewater containing dye that become major environmental concern. The disposal of dye wastewater without proper treatment can cause harm for the aquatic species and environment. EF has good efficiency of color and dyes removal from the waste water. EF efficient technique of removal of the color and dyes from the textile waste water. Cost of this type of process is lowest than the conventional method. Analysis of the removal of color and dyes from textile waste water at various pH, Contact Time and the Concentration of color and dyes shows the optimum values of all parameters. Color and dyes can easily adsorb from textile waste water by EF and high efficiency. The percentage of color and dyes adsorbed increases with the pH. The percentage of each metal adsorbed as function of the pH. The maximum adsorption of color and dyes occurs at pH range between 5 and 6. As per observation the efficiency of color and dyes adsorption is related with the contact time as contact time increase percentage of color and dyes reduction increase. The maximum adsorption is noticed between time of 120-150 min for color and dyes at concentration of 5-10 ppm with pH value 5-6. After these optimum value removal of color and dyes are constant. As concentration increases % removal decrease at particular stage after that rate of adsorption constant. As concentration increases % removal decrease at particular stage after that rate of adsorption constant. The optimum value of concentration of dyes between 5-10 ppm. The maximum dyes removal from textile waste water up to 90 % between contact time 120 min, 5 ppm and pH value 5-6.
