EVALUATION OF POLLUTANTS OF TEXTILE MILLS EFFLUENTS IN NCR-DELHIPARESH KUMAR, GAURAV SINGHALAND VIPUL BHARDWAJ
The main pollutants come in textile effluents from dyeing and finishing processes. To assess the pollution impact of textile effluents, eight textile industries effluent samples have been collected and analyzed their physico-chemical parameters like colour, pH value, electrical conductivity, total dissolved solids, suspended solids, BOD, COD, BOD/COD ratio, oil and grease by standard procedures. The electrical conductivity, Total dissolved solids, Total suspended solids; Chemical oxygen demand and Biochemical oxygen demand of samples are over permissible limits of standards. The pH value of all effluent samples were very alkaline in nature, electrical conductivity of S1 9650µmho/cm, S5 8970 µmho/cm and S6 8950 µmho/cm, TDS of samples S1, S5 and S6 were 5460mg/L, 5100 mg/L and 4970 mg/L respectively show very high TDS as compared to other samples. Suspended solids of S5 320 mg/L, S1 310 mg/L and S3 305 mg/L were very high as compared to others. COD and BOD values of all samples were very high as compared to standards. It is concluded that the effluent samples of textile industries were highly polluted and serious problem for living being and ecological environment.
