ABSTRACT

Large amount of waste water production and discharge by different industries leads to a serious problem of our surrounding environment. Textile dying industries generate large volume of toxic waste water and thus becoming the highest polluter of the ground water. Dyeing yarns is one of the most important auxiliary occupations of the weaving sector. Hundreds of people are engaged in the dyeing process at Shantipur (23.25°N, 88.43°E) in the district of Nadia, West Bengal. Samples of waste water are collected from eleven textile dyeing units for physiochemical analysis. The present study showed that most of the waste water parameters viz conductivity, chloride, COD and BOD of eleven factories of this area are crossed the maximum permissible limit of Indian Standard The result of BOD/COD ratio also indicates that the effluents of these dyeing units have a large percentage of non-biodegradable matters. Awareness and regular monitoring of waste water may reduce the environmental stresses and should be mandatory for every dying factory.
