Constructed Wetlands (CW) are engineered wastewater treatment systems
filled with porous media and planted with emergent wetland plants. The aim of this
study was to analyze the phytoremoval effectiveness by Typha angustata and
Phragmites australis to treat Sugar industry effluent in CW systems as vertical flow
subsurface treatment. Local wetland soil CW showed significant improvement in all
parameters. Phragmites australis gave 98.84% reduction in COD and 99.69% BOD
whereas ammonical Nitrogen and organic Nitrogen was totally removed from the
effluent. Treatment using Typha angustata reduces COD 76.90% and 89.21% BOD
while NH3-N and organic Nitrogen were reduced 89.42% and 78.57% respectively.
The results were also statistically verified using one way ANOVA and 2 tailed t-test
Analysis. The study shows that sugar industry effluents treated in vertical flow
subsurface wetland with Phragmites australis gives best reduction in all the
parameters of water with retention time of 7 HRT.
