Textile industry plays an important role in the economy of the country like India
and it accounts for around one third of total export. Textile industry is one of the
main source of pollution problem worldwide. Textile effluent is characterized by
high BOD (from 700 to 2,000 mg/l) and COD loads, suspended solids, mineral oils
and residual dye. 10-25% of textile dyes are lost during the dyeing process, and 2-
20% is directly discharged as aqueous effluents in different environmental
components. Traditionally produced fabric contains chemical residues, used during
their manufacturing. These chemical residues may evaporate in air or may absorb
through our skin thus causing allergy. According to a June 5, 2005 article in
business week, the population allergic to chemicals will grow to 60% by the year
2020. The paper deals with the various operations involved in the textile industry
and discusses about the water usage and wastewater characteristic of textile
industry. It also gives a brief idea about the treatment technologies for treating
waste water.
