The problems created by textile wastewater getting more serious concern especially in developing countries. This is due to the low biodegradation of dyes and chemicals used in the commercial textile are hazardous and dangerous to the environment. Due to the low biodegradation of dyes, the conventional biological treatment process is not very effective in treating dye waste. To overcome these problems, the research for environment-friendly and low-cost treatment is essential. This experimental study is carried out to find the quality of dyeing wastewater in the textile industry by assessing the physiochemical characteristics and heavy metal concentration. For this study, fifty liters of dyeing wastewater is collected from a dyeing unit at Tirupur. Ferrate is a potential water treatment chemical used for treating dyeing wastewater due to its dual functions as an oxidant and a coagulant. High valent oxidants such as ferrate (IV), ferrate (V) and ferrate (VI) are added to the dyeing wastewater from the textile industry and various pollutants are removed. The treatment is done for a period of 15 days and the parameters are recorded for consecutive days (1, 5, 10 and 15). On comparing the three oxidants, ferrate (VI) proved to be very effective in reducing the concentrations of tested parameters.
