Decolourisation and Treatment of Textile Waste Water

The textile industry effluent water reactive dyes have been identified as problematic compounds in textile industrial waste water as they are water soluble and cannot be easily removed by conventional treatment process. Textile and dyeing industries are responsible for contaminating water due to discharge of coloured effluence, so water pollution due to colour from textile and dyestuff industries is major concerned today. The removals of dyes present in these industrial effluence have been received great potential in last few years. It was estimated that was about 12-15% of these dyes are released in effluents during process causes environmental pollution. This project deals with eco-friendly treatment of textile wastewater by adsorption method using rice husk. The characteristics of textile wastewater before and after treatment are analyzed and compared. The reuse of treated textile wastewater has a wide range of application in irrigation, since it is within the irrigation standards. In this project, we evaluate performance of carbonated rice husk for removal of pollutant such as chemical oxygen demand (COD), Biochemical oxygen demand (BOD), turbidity, pH, Total suspended solids (TSS), Total dissolved solids (TDS), Chlorides, hardness.
