Selection of Technology to Treat Waste Water Generated from Dye Intermediate Manufacturing Industry: A Case Study

Anand P. Dhanwani, Srinivasarao Meka, Shrey B. Patel

In this paper, we address the problem of treating waste water generated from manufacturing unit producing Dyes and Dyes Intermediates. We have considered three alternative technologies ie. Multiple Effect Evaporator (MEE), Incinerator, Electrochemical Treatment (ECT). MEE is found to be more economical compared to the other two technologies. Selection of MEE reduces the quantum of solid waste disposed and also improves the quality of effluent. The efficacy of the results presented are demonstrated by taking a case study of manufacturing unit producing Dyes and Dyes Intermediates located in GIDC Ahmadabad, India.
