The current research demonstrates the capability of water hyacinth (Eichhornia crassipes), a floating aquatic plant, used for treated of municipal landfill leachate. Experiments were carried out to investigate the ability of water hyacinth to remove different salinity ions concentrations. The ability of water hyacinth to remove some parameters such as nitrogen, phosphorus, and organic material as COD were also investigated. All experiments were conducted in batch reactors in a greenhouse environment. The leachate samples were collected from Benowo Landfill. The concentration of salinity in leachate was 6.8 ppt, under range of mesohaline. Concentration of organic material and ammonium was also high. Based on range finding tests were founded that water hyacinth not effective to remove of salinity within concentration as high as 3 ppt. The maximum concentrations of salinity for this treatment was 2.5 ppt. Presence of salinity were inhibit the growth of the plant and decrease capability of water hyacinth to remove pollutants. Removal efficiency for removing of salinity as high as 49% in which concentration of salinity is 0.6 ppt. Uptake of ammonium, phosphate, and organic material was decrease with increasing concentration of salinity
