RESUMO
One of the major problems encountered in the textile industry is the production of large volumes of highly coloured wastewater. The textile industries daily discharge million litres of untreated effluents in the form of wastewater into public drains that eventually empty into rivers. They cause serious health hazard. Textile wastewater also contains substantial pollution loads which increase the Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Suspended solids (TSS), Total Dissolved Solids (TDS) and heavy metals. So pre-treatment is needed prior to discharge of these effluents. Among all method investigated presently, Phytoremediation by AMATS (Aquatic Macrophytes Treatment Systems) is a well established environmental protective technique. The most common aquatic Macrophytes being employed in wastewater treatment are water hyacinth, penny wort, water lettuce, water ferns and duck weeds, because they are cheaper to construct and a little skill is required to operate them. This review paper discusses comparative study and efficiency of plants and proposed mechanism of various plant contributed for remediation of textile waste water.
