Abstract:
In this present work, the ability of Moringa seed extract–among other natural coagulants–to remove different types of dyes has been researched. Moringa stenopetala seed has been demonstrated to have high removal ability for anionic dyes. Because, textile wastewater is one of the most sources of pollution. This wastewater containing higher value of color, BOD, COD and several pollutants. If being directly discharged without treatment, it will bring serious problem to the ecological environment. Now days, the numbers of textile industries are increasing which threat the environment so the main finding of this work is to reduce the impact of wastewater. This study is particularly focused on testing the removal of dye wastewaters such as reactive dyes, direct dyes, mixture of dye wastes and mixture of industrial and dye wastewaters. The seeds of the Moringa tree contain a coagulant protein that can be used in the treatment of industrial wastewater. Therefore, the purpose of this study was to evaluate the effectiveness of Moringa seed as a coagulant for textile wastewater treatment. The effect of some operating parameters on coagulation namely pH, coagulant dose, mixing time, color removal and turbidity should be studied. From the results it was observed that the color removals in direct red and reactive red dyes are 94.45 and 98.4% respectively in simple extract. These dyes itself have highest value of color removal in saline extract about 96.6 and 97.3% respectively. These values of color removal of dyes are optimized at 70ml/L of coagulant and pH 10. Finally the mixture of industrial wastewater and dye wastes color removal and turbidity removal capacity is 85.8% in simple extract and 53% in saline extract respectively at optimized point.
