Abstract

Pollution is being one of the major problems that lead to a miserable condition in human and aquatic life. Among the many kinds of pollution, at present the most important one is the waste from textile industry which releases the wastewater containing dyes and processing chemicals. In the present investigation, our aim is to evaluate the suitability of the textile effluent samples collected from various textile units of Karur region, for discharge directly into aqueous bodies without treatment. The physicochemical analysis of the untreated textile effluent samples viz., pH, TDS, TSS, BOD5, COD, Total alkalinity, sodium, sulfate, phosphate, chloride and heavy metals concentration viz., chromium, cadmium, copper, iron, nickel, lead and zinc were carried out. It is concluded that the effluent is not be suitable for discharge directly into aqueous bodies without treatment.

Keywords: pollution, dyes, heavy metals, physicochemical, textile effluents.
