Textile industry is one of the most important and rapidly developing industrial sectors in Ludhiana city of Punjab, India. It has a great disadvantage in terms of its environmental impact because it consumes considerably high amount of processed water and produces highly polluted discharge water. To control the polluted discharge the Textile mills in India have started to install treatment plants in the name of environmental protection. The wastewater from 7 textile mills in the woven fabric and knit fabric finishing industry and one highly polluted drain, locally known as Buddha Nala, which receives discharge from many such industrial units, were collected for the study. Performances of the treatment plants were evaluated by site inspections and analyses of influent and effluent samples.

For the treatment of wastewater from textile industry, biological treatment, chemical treatment and combinations of these processes have been used. Plants utilizing biological treatment rather than chemical processes claim that their preference is due to less excess sludge production, lower operational costs and better Chemical Oxygen Demand (COD) removal in biological treatment. Waste water parameters in the effluent of biological treatment plants were not in compliance with the waste water and sewerage discharge standards.

However, if sodium sulphate in dying process and sulphuric acid in neutralization processes are used before a biological treatment, sulphate in the effluent exceeds 1700 mg/l.This problem can be avoided by using HCL or CO2 rather than H2SO4 in neutralization and NaCl instead of Na2SO4, if the use of Na2SO4 is not necessary.
