The limitation of water resources has led to demands for the development of alternative water resources. Currently, interest in wastewater reuse in industrial sector has promoted the development of wastewater treatment technologies. Textile industry is known as an intensive water use sector. The majority of water is utilized in wet processes such as dyeing, sizing and finishing. Thus these processes generate very large volumes of wastewaters which are generally with intense color, high concentration of organic compounds and large variations in composition. Indigo is a well-known color dye used for denim industry. Water bodies polluted by denim industrial wastewater can affect oxygen and nitrogen cycles through photosynthesis and also may be toxic to aquatic biota. Recently, there are an increasing number of studies focused on introducing advanced treatment technologies such as membrane processes to assess the potential for reuse of water. Although, there are many wide range of investigations have been done in the application of membrane bioreactors (MBRs) for textile wastewater treatment, very scarce studies have investigated the application of MBR for denim wastewater treatment. Moreover, membrane-fouling of MBR lead to higher operation and membrane replacement cost. Therefore, the aim of the present work is to investigate and compare the performances obtained during the simultaneous operation of MBR and bioaugmented MBR with decolorized bacteria isolated for the enhancement of color removal...
