Abstract

Accepted 27th October, 2014

 

Pollution is an important problem in human and aquatic life that leads to a miserable condition. There are many kinds of pollution but textile industry is mainly by the release of wastewater containing dyes and chemicals, coming out from wet processing like de-sizing, scouring, bleaching, mercerizing, dyeing, printing and finishing. In present investigation, the physico-chemical analysis and heavy metals concentration are pH, TDS, TSS, BOD5, COD, Total alkalinity, sodium, sulfate, phosphate, chloride, chromium, cadmium, copper, iron, nickel, lead and zinc were found within the permissible limits. Concentrations of all these metal ions in the effluent were above the recommended NEQS. The effluent samples were evaluated to ascertain the efficiency of industries wastewater treatment process. Conventional methods were employed for determination of physico-chemical parameters while; heavy metals in the textile effluent sample were analyzed using an Atomic Absorption Spectrophotometer (AAS).
