An investigation of textile wastewater treatment using chlorella vulgaris

Abstract

An uptake system for the bio-remediation of textile wastewater using Chlorella vulgaris DPSF01. Chlorella vulgaris is mass cultured in raw textile wastewater diluted with normal tap water and the growth was assessed. The research work focus on to evaluate the potential of Chlorella vulgaris on reduction of physicochemical properties and azo compounds in textile wastewater.Treatment of textile wastewater with C. vulgaris is carried out for 28 days. The microalga is inoculated on four dilutions (15%, 30%, 45% & 60%) of textile wastewater. Cell count of Chlorella vulgaris and physicochemical parameters of the treated and untreated wastewater is enumerated once in seven days interval for 28 days. Degradation of azo compounds on treated and untreated wastewater by Chlorella vulgaris was confirmed by GCMS and FTIR analysis. The results confirm that Chlorella vulgaris DPSF01 has improved the quality of textile wastewater to meet its permissible limits for discharge into the environment.
