Water has been one of the most affected by industrialization and the development of the textile sector. Medellin is the fashion capital of Colombia and city daily use cleaners dedicated to clothing indigo dyeing. They are major consumers of ground and drinking water. Water is used with minimal consciousness, its increased raw material and which generates high monthly costs. This study was built (RLF) fluidized bed reactor. The anthracite was used as support material for investigating the efficiency removed of the chemical oxygen demand (COD), demand biochemical oxygen (BOD) and color of simulated textile wastewater. Following studies at laboratory scale were initially made to prepare the immobilization of microorganisms in the middle of solid support and periods of start-up and operation of the pilot plant testing: bioaugmentating and bioadaptacion seed taken from textile effluent and removal of color in discontinuous reactor. The results indicated that it is possible to achieve aerobic treatment of textile waste water after obtaining an inoculum adapted to sources of carbon of surfactants, and Indigo.
