Water hyacinth (Eichhornia crassipes)
treatment systems are generally known in tropical
areas. The system with water hyacinth can operate
at higher loading rates. Their end-use products can
be utilized for mulch and organic fertilizer. Dry
water hyacinth petioles can be woven into baskets
and purse (Polprasert, 1996). Beside that, they are
many potential aquatic plants that can be used for
wastewater treatment but they have not been
investigated or there is a lack of data collections.
This study aims to investigate the efficiency of
unconventional plants for aquatic treatment system
such as lotus (Nelumbo nucifera) and hydrilla
(Hydrilla verticillata) as the substitution plants in
tropical zones.
