Ability of Rhizophora mucronata and Avicennia marina seedling for municipal sewage treatment in different mangrove soil textures were designed using 4 experiment soil textures; soil, soil:sand (3:1), soil:sand (2:2) and soil:sand (1:3) and 2 species of mangrove seedling (R. mucronata) and A. marina) and a control without plant. Comparative ability of municipal sewage treatment by 2 species of mangrove seedling in different soil texture indicated that ability of municipal sewage treatment in 4 experiment soil had no significant differences and R. mucronata and A. marina can treated municipal sewage better than those of no plant experiment (p<=0.05). R. mucronata can remove BOD 59.60-72.08%, Ammonia-Nitrogen 84.47-89.46%, Nitrite-Nitrogen 57.61-66.89%, Nitrate-Nitrogen 59.09-67.90%, Total Nitrogen 64.64-72.47%, Ortho-phosphate 51.49-68.30% and total phosphorus 53.77-63.06%. A. marina can remove BOD 62.31-66.32%, Ammonia-Nitrogen 80.23-84.47%, Nitrite-Nitrogen 52.29-66.64%, Nitrate-Nitrogen 55.61-69.20%, TotalNitrogen 64.44-70.08%, Ortho-Phosphate 48.57-60.49% and Total Phosphorus 51.40-62.68%. And no plant growing can remove BOD 48.53-57.58%, Ammonia-Nitrogen 58.69-75.71%, Nitrite-Nitrogen 38.03-58.43%, Nitrate-Nitrogen 37.07-48.64%, Total Nitrogen 53.28-58.83%, Ortho-Phosphate 43.30-54.77% and Total Phosphorus 48.58-58.67%. Total nitrogen in all soil textures had no change after the experiment, but total phosphorus significantly increased after the experiment (p<=0.05), the highest organic matter was found in soil. The highest growth rate and biomass increment or R. mucronata was found in soil experiment, followed with soil:sand (3:1), soil:sand (2:2) and soil:sand (1:3), respectively, and nutrients in leaf significanty increased after the experiment (p<=0.05). The growth rate and biomass of A. marina are the lowest in soil while there is no significant for all another experiments. The results suggested that municipal sewage nutrients can be satisfied removed with R. mucronata and A. marina. The experiments with plants showed higher percent removal of nutrients.
