From our screening of 5 plants including Nelumbo nucifera
Gaertn., Cyperus alternifolius L., Nymphaea sp., Nymphaea pubescens
Willd and Typha angustifolla L. for phosphorus removal from domestic wastewater, N. nucifera Gaertn., C. alternifolius L. were
found to be the best in phosphorus removal. Therefore, these two
plants were selected for further study. In addition, N. nucifera grows
well in swamp or pond, and uptakes high amount of water while
growing. C. alternifolius tolerates to un-favorable condition and
easy propagation. The two plants have good characteristic for use in
remediation system.
