- Abstract
Eight halophytic plant species, Avicennia marina, Avicennia alba, Bruguiera gymnorrhiza, Lumnitzera racemosa, Rhizophora mucronata, Rhizophora apiculata, Suaeda maritima, and Xylocarpus moluccensis were evaluated for the removal ability of total dissolved solids (TDS) from plastic industrial effluent. All halophytic plants could tolerate and survive when grown in wastewater with high TDS. Among the test plants, S. maritima showed the highest TDS removal capability and was selected for further study. S. maritima had ability not only for TDS removal, but also for reduction of pH, electrical conductivity, and salinity from wastewater effluent under soil conditions. S. maritima did not exhibit symptoms such as necrosis and leaf tip burn during the experimental period. These results indicated that S. maritima has tolerance to high TDS and salinity. However, S. maritima responded to high TDS stress by producing proline and total sugar in the roots, stems, and leaves which indicated that this plant can adapt to wastewater with high TDS. In addition, silicon (Si) and calcium (Ca) were increased in the leaves due to plant stress from TDS. Therefore, S. maritima is suitable halophytic plants for treatment of TDS contaminated wastewater.
