Abstract
This study presents treatment of domestic wastewater collected from the Harmony Lodge Ifite Awka,
Anambra state using laboratory scale constructed wetland vegetated with Cyperus esculentus(tiger nut)plant as
biofilter.to determine the removal of pollutants. The study was conducted from August 19th 2016 to September 2016, at
Nnamdi Azikiwe University laboratory, Awka. Result of laboratory analysis on samples of wastewater collected showed
reduction in pollutant of nitrate 50%, phosphorus 42%, ammonia 36%, COD 59%, BOD 70%, pH range was changed
from 6.59 to7.15. Analysis of Variance (ANOVA) was used to analyse data obtained. Differences in parameter
concentration between the influent and effluent parameters and also between effluents for three detension periods were
considered significant at 5% level of significance (i.e p . The concentration of these parameters decreased
significantly as a result of the treatment. This shows that the cyperus plant is effective in pollutant removal from
domestic wastewater.
