Water is an irreplaceable natural resource on this earth which includes marine, estuarine, fresh water (rivers and lakes), groundwater in coastal areas and interior. Even though there are enormous water resources in this world, about 97% of the water is salt (marine) water, and only 3% is fresh water. And of this small fraction of fresh water, much of it is found as ice in the polar region. So only 0.003% is in the form of groundwater and surface water that we can use. Fresh water is a limited resource in many parts of the world. And this will result in increased shortages due to population growth, urbanization and climate change. The major problem of this shortage of fresh water is not only due to the demand for water, but also the pollution of the fresh water ecosystem. Due to the pollution created by humans in this ecosystem, usable water has decreased significantly and the cost of water purification has increased significantly. The main sources of water pollution are point sources and diffuse sources. Point sources include pipeline discharge of pollutants such as domestic sewage, industrial effluent from factories or factories, to receiving waters. In contrast, diffuse pollution results from storm runoff, which transports polluting materials diffusely over land. Water pollutants are of different types such as oxygen demanding wastes, pathogens, synthetic organic compounds, plant nutrients, inorganic chemicals and minerals, oils, thermal discharges and radioactive wastes. Among all these water pollutants, heavy metals and synthetic organic compounds cause the majority of water pollution. Industries like paper and pulp, tanneries, textiles and coke ovens, paper and paper industries, textile industries are considered as one of the major sources of waste water in countries of ASEAN. Dyes are also used in industries such as rubber, paper and pulp, intermediate dyeing and dyeing industries, pharmaceuticals, tanneries, food technology, hair coloring, plastics, cosmetics , etc. There are over 10,000 commercially available dyes with over 7 x 105 tonnes of dye. produced every year around the world2. The textile industry consumes more than 107 kg of dye per year, 90% of which ends up on fabrics3. Of this total usage, 10-15% of the dye is lost during the dyeing process and discharged with the effluent. Color is provided by phenolic compounds such as tannins, lignins (2-3%) and organic dyes (3-4%) and with maximum contribution from dyes and dye intermediates which could be sulfur/ mordant/reactive/cationic/dispersed/acidic. /azo vat dye4.
