Wet Processing of Textiles: Health and Environment
Abstract: Though the Indian textile industry has its importance in the national economy, but at the same time it is responsible for disastrous environmental impacts. These impacts start with the use of pesticides during the cultivation of plants, from which natural fibers are obtained and with the erosion caused by sheep farming or with the emissions during the production of synthetic fibers. From that moment, a number of processes are applied …

Biodecolorization of Textile Dye Effluent by Biosorption on Plant Biomass and Equilibrium Modelling
Abstract: AbstractDye effluent discharge into water bodies leading to water pollution. Each textile dye process requires a different amount of dye and also it generates a different amount of effluents. Most of the physico-chemical methods are insufficient and highly expensive. Biosorption is an alternative technology for the treatment of different textile and other effluents. Aquatic plants specially water hyacinth showed a greater potential to use as biotrap for textile effluent treatment. …
