Water hyacinth (Eichhornia crassipes) was supplied by the J Food
Industry company in Korea and transplanted to the pilot plant. Water
hyacinth productivity was measured using a basket (L=1m×W=
0.6 m, area=0.6 m2, wire gauge type) which was set in WHP cell #2.
Periodically, this basket was taken out of the WHP, and plant weight
in the basket was measured after the water was removed. The total
water hyacinth productivity in the WHP was obtained by considering
the total area of the WHP.
