Analysis of Impact of Textile Dye Industries on Underground Water in Jaipur Region

摘要

In this paper an attempt has been made to study the impact of textile dye industries on underground water in Jaipur region and to design a low cost method for treatment of dye stuff wastewater. Samples of underground water from 3 different locations in the study area and wastewater from textile dying industries from various stages of dying were collected, to get a broad perspective on the impact of disposal of wastewater on groundwater quality and also to assess the potential adverse effects of wastewater from various stages of textile dying industries on environment, since it is directly being used for irrigation purposes. It was concluded that though not much harm has happened to the underground water in any of these locations but the same was not fit for drinking either. Out of the 3 locations, Bagru had the worst situation followed by Sanganer and Muhana. The unit successfully eliminated arsenic and lead fully and achieved about 75% reduction in fluoride, chloride and turbidity. Chemical oxygen demand got reduced from 422.6 to 132.5 mg/L, which was highly desirable for reuse by the industry itself.
