TREATABILITY STUDIES OF SIMULATED DYE HOUSE EFFLUENT OF ANIONIC DYES (A HYPOTHETICAL APPROACH)

摘要

Simulated dye house effluents, adsorption, low cost adsorbents%The textile industry is one of the largest industries in world & is among the major waste generating industries. Number of physical and chemical treatments are followed by industries to control the waste water effluents. But the functional and operational cost for the processes is high. So continuous efforts are being done by scholars to search the alternatives. In the present study efforts have been made to evaluate whether any improvement in treatment of dye house effluent is possible through use of adsorption technique followed by Aerobic/Anaerobic treatment. Batch studies& continuous studies were conducted using low cost adsorbents such as Sugarcane baggase, Rice husk and Saw dust without activation. Colors used were C.I. Reactive Red 120, C.I. Reactive Blue 198 and C.I. Reactive Yellow 135.Simulated effluents were treated using adsorption technique followed by aerobic/anaerobic treatments and results were compared with the standard norms of pollution board .Application of this technique was also subjected to textile industries dye house effluents & results were compared with the actual results of ETP of the industries. Cost benefit analysis was also carried out which show that there is huge savings if the industries opt for the adsorption of the textile dye house effluents followed by anaerobic treatment.
