Evaluation of Treatment Plant Efficiency Using Toxicity Index – A Case Study of Textile Industries

Abstract

Evaluation Of Treatment Plant Efficiency Using Toxicity Index-A Case Study Of Textile Industries The present study has been undertaken to evaluate performance efficiency of a waste water treatment plant. A sewage treatment plant operating on biological treatment method (Activated Sludge Process) with an average wastewater inflow of 23MLD bas been considered for case study.

Waste water samples were collected at different stages of treatment units and analysed for the major water quality parameters, such as biological oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS) and total dissolved solids (TDS). Theperformance efficiency of each unit in treating the pollutants was calculated. Overall performance of the plant also has been estimated.

Conclusion

Cleaner production is an attractive approach to tackle environmental problems associated with industrial production and poor material efficiency. Since the cleaner production approach has been successfully implemented in some areas in the textile sector, it shows that significant financial saving and environmental improvements can be made by relatively low-cost and straightforward interventions.
