Abstract :

Constructed wetlands (CWs) are ‘‘engineered systems, designed and constructed to utilise the natural func –tions of wetland vegetation, soils and their microbial populations to treat contaminants in surface water, groundwater or waste streams”. The aim of this study was to analyze the phytoremoval effectiveness by Typha angustata  and Phragmites australis to treat Detergent industry effluent in CW systems as vertical flow subsurface treatment. Local wet –land soil in CW showed significant improvement in all parameters. Phragmites australis gave 93.33% reduction in COD and 95.14% BOD whereas Ammonical Nitrogen was totally removed from the effluent and organic Nitrogen was removed upto 95.41%. Treatment using Typha angustata reduces COD 58.65% and 87.16% BOD while Ammonical Nitrogen and organic Nitrogen were reduced 39.76% and 56.79% respectively. The results were also statistically verified using one way ANOVA and 2 tailed t–test Analysis. The study shows that Detergent industry effluents treated in vertical flow subsurface wetland with Phragmites australisgives best reduction in all the parameters of water with retention time of 7HRT.
