| Summary: | Ammoniacal nitrogen (AN) is present in both domestic
and industrial wastewater which is one of the main
contributors of eutrophication. Phytoremediation is
recommended as an alternative solution to treat
wastewater with high AN content due to its costeffective, environmental friendly and sustainable characteristics. In this study, one-factor-at-a-time (OFAT) study was conducted on the parameters influencing the AN removal using water hyacinth. The variables involved pH (4-10), retention time (2-14 days), initial AN concentration (10-70 mg/L), macrophytes density (5-30 g/L) and salinity (1-5 g NaCl/L) which influenced the AN removal
significantly. The highest AN removal of 98.85% was
obtained at pH 9, 99.18% at retention time of 14 days,
90.46% at initial AN concentration of 40 mg/L, 84.91%
at macrophyte density of 30 g /L and 70.13% at salinity
of 1 g NaCl/L respectively. Overall, water hyacinth has
demonstrated high potential as the macrophyte for
phytoremediation of AN in semiconductor effluent. |
