ABSTRACT

 

In the present study the characteristics of the untreated wastewater generated from dyes and dye intermediates industries was studied. Wastewater of 10 unit manufacturing different types of dyes and dye intermediate were used for this study. Wastewater was analyzed for pH, Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Total Dissolved Solids (TDS), Suspended Solids (SS), chloride, ammonical nitrogen, phenolic compounds, hexavalent chromium, total chromium, nickel, oil and grease. The study shows that high amount of sludge was generated from treatment of wastewater. The study also shows that the treated wastewater does not meet the discharge norms provided by Gujarat Pollution Control Board, Gujarat, India. The study also correlated manufacturing process with wastewater characteristics and shows that the wastewater is a mixture of wastewater generated from various stages of manufacturing process. Therefore, the segregation of wastewater generated from different stages of manufacturing process shall be collected and studied for its treatment.

 

Keywords : Dye industries, Segregation of wastewater, Manufacturing process, BOD, COD, Total Dissolved Solids
