摘要：Phytoremediation by using aquatic plants and microalgae was evaluated in study to reduce waste load of Palm Oil Mill Effluent (POME). This study was aimed to utilize the aquatic plants i.e. water hyacinth ( Eichhornia crassipes ) and water lily ( Nymphaea sp.) and alga Spriulina sp. to reduce COD and nutrients content in palm oil mill effluent . The phytoremediation was conducted in a sequence process. The aquatic plants were used in the first stage of remediation by varying height of culture (5-15 cm), length of remediation (3-8 days) and type of plants (water hyacinth and water lily). The effluent of the first stage was then transferred to the second remediation where microalgae Spriulina use this effluent as medium growth for 15 days. The results showed that the aquatic plants was able to reduce COD, N, P up to 50, 88 and 64%, respectively, while microalgae could reduce the COD, N, P up to 50.79, 96.5 and 85.92%, respectively. The maximum growth rate of Spirulina platensis was 0.412 day^-1, while the correlation between Optical Density (OD) and dry weight-g L^-1 was shown as dry weight (g L^-1) = 0.782.OD. In conclusion, two stage phytoremediation process gives promising method to reduce waste load and producing high value able biomass of algae.
