ABSTRACT

The disposal of industrial waste is one of the burning issues faced by the world today. The present study reveals the detailed analysis of industrial dye effluent at different sites of Jodhpur and Balotra. The research area focused around Sangariya and Salawas in the Jodhpur and industrial area of Balotra. The industrial waste of industries in these areas was directly discharged into nallah which was then carried to Jojari and Luni rivers, respectively. The various physico-chemical parameters estimated in wastewater samples remarkably differed with the change of location of sites. The results obtained exceeded the maximum
permissible limits set by Indian standards devised by W. H. O. The results of the physico-chemical analysis of sample from different locations obtained were in the following ranges pH (> 8.2 <), conductivity (4930-11900 ┬ÁS/cm), TDS (2647-7650 mg/l) and total hardness (30-1875 mg/l), sulphate (96-720 mg/l), chloride (1064-4432 mg/l), SAR (13.25-83.98 meq/l) and RSC (0-21.6 meq/l). BOD and COD of the collected
effluent samples were determined, which ranged from 400 and 1200 mg/l. A tentative correlation between prevailing water-borne diseases and excessive chloride, sulphate, dissolved solids in the water of Jodhpur
district areas were also obtained.
