Dyes and coloring pigments are used as a solution which sticks to wherever it is applied and gives an appealing look to the article and serves other coloring purposes. Dye and pigments industry directly or indirectly serves the paints and coatings, textile, printing ink, plastic and other end-user industries.
Unique challenges faced by textile dye and pigment industries.
In the textile industry, up to 200,000 tons of dyes/pigments are lost to effluents every year during the dyeing and finishing operations, due to the inefficiency of the dyeing process. Unfortunately, most of these dyes escape conventional wastewater treatment processes and persist in the environment as a result of their high stability to light, temperature, water, detergents, chemicals, soap and other parameters such as bleach and perspiration. Dyes are also used heavily within the textile industry. The effluent wastewater that is produced from the dying process can contain salt, sulfites and of course unused dye. Loss of some important constituents has adverse impacts on the process operation, operation costs, conventional recovery processes and fails to meet the environmental standards.
