ABSTRACT

 

In this study, performance of a CETP treating 3405 m3 day-1 wastewater from 450 synthetic textile mills was evaluated. Four criteria viz. design, operation, maintenance and administration was deployed to evaluate the overall performance of CETP. Design data was collected from each unit operation of the CETP and adequacy of design was assessed using a scoring method. Actual operational efficiency of the CETP was evaluated by collecting samples (19 in all) at each stage of treatment. All samples were analyzed for 16 physico-chemical parameters. Administration capability and adequacy of maintenance systems were evaluated using questionnaires and by conducting staff interviews. The overall performance of the CETP was evaluated considering all the dimensions and accordingly recommendations were made for improving the performance.
