heal.abstract	Textile Dye and Finishing Wastewater (TDFW) from a reactive cellulosic azo dyeing and finishing process was treated by an electrochemical oxidation method using Ti/Pt as anode and Stainless Steel 304 as cathode. The strong oxidizing potential of the chemicals produced when the wastewater was passed through the electrolytic cell resulted in the oxidation of organic pollutants to carbon dioxide and water. Batch, laboratory-scale and pilot-plant experiments were run and the results are reported in relation to residence time and initial addition of HCl and NaCl in raw wastewater. Addition of higher initial amounts of NaCl and HCl resulted in an improved color and chemical chemical oxygen demand (COD) removal. The COD was removed by 92% when electrolysis was carried out for 40 minutes at 0.89 A/em2 in presence of 2 ml 36% HCl and 1% NaCl. Furthermore, explain in ADMI color units were reduced by 94%, biological oxygen demand (BOD5) was reduced by 92.2%, and total Kjeldahl nitrogen was reduced by 100%. At the same time the efficiency of the electrode was about 80 g h-1 A-1 sq.m-1. and the mean energy consumption was 44 kwh per kg of COD. These results indicate that this electrolytic method could be used for effective TDFW oxidation.	en
