Experimental Study on Color Removal from Textile Industry Wastewater Using the Rotating Biological Contactor

Volume 14, Issue 4
Abstract
Textile industry wastewater treatment is a cause for concern due to its intense color and high COD, which makes it difficult to treat it by conventional treatment options. Also, many of the dyes used in the industry fall under the category of hazardous wastes and are known to be toxic to microorganisms and aquatic life forms. An experimental study was conducted to observe the performance of Rotating Biological Contactor (RBC) system for color and COD removal from textile industry wastewaters. The RBC system could achieve up to removal of color and removal of COD in all four stages of RBC under optimum operating conditions. The first two stages of the RBC showed up to of color and of COD removal. The biofilm study concluded that a mixed culture of microorganisms (both bacteria as well as fungi) was responsible for the treatment of textile industry wastewater and the recovery of the RBC system could be very fast in case of any shock-loading occurred.

The writers would like to thank the Ministry of Environment and Forests (MoEF), Govt. of India, for providing financial assistance to complete the research project successfully. The writers would also like to thank Mr. Suresh and Mr. Raje Singh (Technical Assistant, Environmental Lab, IIT Delhi) for their continuous support and help in completing the project. At last but not the least, the writers would like to give their special thanks to industries for providing the wastewater, without which, the study would not be possible.
