Abstract
Abstract for presentation in session: Environmental-Biotechnology
Synthetic chemical Dyes are coloured substances most extensively used in Textile industry worldwide, and several dyes have applications in other industries like leather and paper. There are about 10,000 different types of dyes available and their annual global production is estimated to be 70,000 tons. Approximately 10-20% of production is lost during the dyeing process. The effluents containing synthetic dyes are toxic for microorganisms, human beings and aquatic life, if disposed without a proper treatment in water bodies. Humans exposed to synthetic chemical dyes-contaminated water can get skin irritations and in long-term might suffer with dermatitis.
Due to the environmental hazards, dyes removal from effluents before its safe disposal in water bodies is an important legal issue. Various physico-chemical methods, such as precipitation, adsorption, flocculation, reverse osmosis etc. have been used for the treatment of coloured water but these methods lead to the formation of solid sludge, which requires further treatment. Dyes can also be biologically degraded, but then this is a very slow process and hence, not practical for the treatment of vast volume of effluent generated each day from industries. Photocatalytic degradation employing photocatalysts, has been reported an efficient method for the complete mineralization of azo dyes, but the cost of catalysts and process assembly and monitoring makes overall process expensive.
Our work was undertaken with an eco-friendly and economical approach to treat coloured water, with important objectives: 1. Removal of dyes from coloured waters using zero-cost bioproducts; 2. Faster process to deal with larger volumes of effluents produced in industries; 3. Treatment of by-products used in the removal of dyes for their safer disposal in environment. Process and outcomes will be discussed in presentation.
