Physico-Chemical Characterization Of Textile Effluent From A Dyeing Industry In Tiruppur Of Tamil Nadu

The physico-chemical parameters of various textile industrial effluents vary depending on the type of dyes and processingchemicals used. The major pollution indicating parameters like TS, TDS, TSS, DO, COD, BOD, pH, alkalinity, chlorides,sulphates and heavy metals were analyzed. The estimated parameters were compared with the stipulated standard values putforth by WHO, BIS and TNPCB. The effluent was highly turbid with high values for TDS, TSS, alkalinity, chlorides,sulphates and iron. The study also showed elevated levels of some heavy metals. Physico- chemical analysis indicate that theeffluent samples have higher values for most of the parameters and exceed the permissible limits. Based on the estimatedcharacteristics, it is revealed that the effluent is not suitable for direct discharge into water stream and need a suitabletechnology for the treatment before discharge.
