Abstract: Ammonia biosorption
by using Enceng
Gondok, Eichhornia crassipes,
was conducted in outdoor
laboratory with objective
to study the
influence residence time
and plant age to
ammonia biosorption rate. The research uses reactor test consisting of wet land
and sludge. Enceng Gondok is planted on reactor test flown by ammonia as bacth
with relatif low enough concentration (2
mg/L), water height 20 cm, plant’s number in each reactor of 4 stems with variatious
plant’s length 10, 20, 30, and 40 cm,
and various residence time 2, 4, 6, and 8 days. Each test conducted was
completed by controlling reactor. Research result showed that maximun biosorption
occurs at 2 days culturization; ammonia
biosorption rate by
roots increases as residence
time increases. Residence
time 2, 4,
6 and 8
days can decrease ammonia concentration
up to 1.568
mg/l, 0.245 mg/l,
0.204 mg/l (10%),
and 0.022 mg/l, respectively, at plant length 10 cm.
Further, research results showed that the more the plant’s age, the larger the
biosorption by plant.
