(Myriophyllum veticillatum Linn.), softstem bulrush (Scirpus
validus Vahl) and yellow-flowered iris (Iris wilsonii),
in showing the water purification through different configuration.
AFIs
with different combination of aquatic plants were set up to purify
the water quality for 50 days. This paper aimed to evaluate chemical
and vegetative characteristics of each type of plant and also to
find configuration of aquatic plants to maximize the contaminants
removal efficiency by artificial floating island (AFI). The result indicated that the trophic waterbody promote
the growth of plants and all of the AFIs
have the ability to purify water and reduce contaminants. However,
the most effective way is by combination of these three aquatic
plants which has strong capacity to remove COD, NO3-,
total nitrogen, total phosphorous and improve pH levels. Watermifoil
(Myriophyllum verticillatum Linn.) is better than yellow-flowered
iris (Iris wilsonii) and softstem bulrush (Scirpus validus
Vahl) in disposing water pollutants. Keywords: Aquatic plants; configuration;
water purification Kertas ini telah memilih tumbuhan
watermifoil (Myriophyllum veticillatum Linn.), softstem
bulrush (Scirpus validus Vahl) dan yellow-flowered iris (Iris
wilsonii) yang menulenkan air melalui konfigurasi berbeza. AFI dengan
kombinasi berbeza tumbuhan akuatik disediakan bagi menulenkan air
selama 50 hari. Kajian ini bertujuan menilai ciri kimia dan vegetatif
setiap tumbuhan yang dikaji di samping mencari konfigurasi tumbuhan
akuatik bagi memaksimumkan kecekapan penyingkiran bahan cemar melalui
pulau terapung buatan (AFI).
Keputusan kajian menunjukkan jasad air trofik menggalakkan pertumbuhan
tumbuhan dan semua kombinasi AFI berupaya untuk menulenkan air dan
mengurangkan bahan cemar. Kombinasi yang paling berkesan adalah
kombinasi ketiga-tiga tumbuhan kerana mempunyai kapasiti yang tinggi
untuk menyingkirkan COD,
NO3-, jumlah nitrogen, jumlah fosforus dan
memperbaiki aras pH. Watermifoil (Myriophyllum verticillatum
Linn.) adalah lebih baik berbanding yellow-flowered iris (Iris
wilsonii) untuk digabungkan dengan softstem bulrush (Scirpus
validus Vahl) dalam menyingkirkan bahan cemar. Kata kunci: Konfigurasi; penulenan air; tumbuhan akuatik RUJUKAN Arts, G.H. 2002.
