QUINTERO, LUZ  and  CARDONA, SANTIAGO. TECHNOLOGIES FOR THE DECOLORIZATION OF DYES: INDIGO AND INDIGO CARMINE. Dyna rev.fac.nac.minas [online]. 2010, vol.77, n.162, pp.371-386. ISSN 0012-7353.

The treatments of textile wastewater containing indigo and carmine indigo are very complex and varied. The efficiency depends on the method used. This article reviews the different technologies for removal of indigo and indigo carmine; efficiencies, microbial cultures, process systems and operational factors to establish criteria for selecting the best treatment process and know the scope of research in the decolorization of indigo. The review begins with the process of fixation of indigo dyeing and then describes studies of treatment of effluent indigo laboratory scale and large scale. There are physical-chemical technology, chemical, physical and biological. The choice of treatment depends on the quality of effluent water, the use, costs of technology, advantages and disadvantages.

Keywords : indigo; carmine indigo; technologies; removal.
