Bioremediation In Textile Industry Essay

Textile industries are important contributor to many national finances. Any industrial action causes pollution in the textile industry. The force of textile production on the environmental aspects such as air, water, land and human body, and the community aspects such as child labour and poor unhygienic working conditions must be considered. Recently, another element is introduced for the environment friendliness of the finished merchandise. This includes the ban on certain azo dyes, which are known or suspected to be carcinogenic. Some of these chemicals, such as dyes and finishing agents, remain attached to the textiles, where as a considerable proportion of these chemicals remains in the water, causes air and water pollution. Many of the

However no universal methods known for the treatment of dye waste waters because of the complex and varied chemical structure of these compounds. In the past two decades research has focused on the complexity of different classes in the waste waters have been recorded. Several treatments are identified as decolourization of the textile or dye containing waste waters. Current treatment technologies for the remediation of dyes in textile effluents have also been illustrated with effective and cheaper alternatives for dye removal and decolourisation on large

Partly due to the new laws requiring stricter protection of the environment and mandating the cleanup of contaminated sites, resources for both basic and applied research on bioremediation by government agencies has increased. This increased activity has led to surge of interest in environmental including microbial, physiology and ecology, molecular genetics, organic chemistry, biochemistry etc. Lab tests that examine degradation rates as functions of critical operating parameters such as ph, oxygen, carbon dioxide, soil particle size ,nutrient concentration etc.

Decolourization is faster when agitation is employed rather than in static reaction conditions. Physio-chemical parameters such as temperature, ph,bioavailability of the substrate determine the bioremediation process. The presence or absence of a particular microbe is not the determinant of the biodegradation process because if the optimal physio-chemical parameters are achieved then the microbes best suited for the biodegradation of the detergent adapted to grow in those physiochemical conditions will automatically
