The textile and dye industries produce waste streams with considerable concentrations of heavy metals and complex organic compounds. There are a number of conventional approaches for the removal of these pollutants but they require a significant amount of capital investment and energy. Some of these treatment processes include coagulation/flocculation/precipitation, reverse osmosis, electro-dialysis and ultrafiltration. Most of these processes reduce the contaminant load to environmentally safe levels but in most cases they produce a large volume of low-density toxic sludge. Alternative bioremediation-based treatment systems have slowly been gaining acceptance in the industrial effluent treatment industry in recent years. Natural organisms are used to break down hazardous substances into less toxic or non-toxic substances. This chapter describes the role of conventional treatment processes and the use of microalgae in the breakdown of complex organic compounds and the concentration and removal of heavy metals from the effluent of the textile and dye industries. |
