Over the last few decades phosphorus removal methods have increasingly been designed. One of the methods is using waterweed for uptake the phosphorus (P) from water and sediment. However, lack information of suitable waterweed for P removal. The goals of this research are to investigate the effect of waterweeds in the P removal and to find the suitable waterweeds for P removal. Five types of waterweeds (Phragmites australis, Egeria densa, Bacupa myriophylloides, Eichornia crassipes, and Limnobium laevigatum) were collected and cultivated in pots. Water and sediment were collected from natural small pond, and sampling were perfomed at 0, 7, 14, 21 and 28 days. The result showed that P of water and sediment were reduced during the experiment. E. densa accumulated highest TP (505 mg/kg). It was suggested that E. densa is suitable for phosphor removal. © Published under licence by IOP Publishing Ltd.
