The Ability of Avicennia Marina in Decreasing Salinity and COD Levels in the Bio-Desalination Process

Rachmi Layina Chimayati, Harmin Sulistiyaning Titah

Abstract: The increasing of residents and increasingly rapid knowledge of technology, the more people demanded it to meet their needs, especially the need for clean water. The worsening quality of clean water has resulted in a reduction in the supply of clean water that was naturally available in the universe. It has been a matter of peerage technology that helps in dealing with the crisis of clean water but leaves a million problems that cause other natural damage, it was necessary to initiate clean water treatment which later would not cause losses or concentrated waste which can damage the natural environment. Bio-desalination using Avicennia marina plants was one of the alternative choices in seawater processing that does not cause concentrated waste where the salt content contained in water would be physically absorbed into plant tissue in a passive transport method. The purpose of this experiment was to determine the ability of Avicennia marina plants for decreasing salinity and COD by bio desalination processes in a reed bed system reactor with batch operation system. The desalination process using Avicennia marina plant has been proven to reduce salinity levels relatively quickly where the ability of the plant for 14 days can reduce salinity. The results showed that the reduction salinity reached 54.74 % at an initial salinity concentration of 15 by Avicennia marina, and it reached 48.98 % at an initial salinity concentration of 25. The reduction of COD in desalination process using Avicennia marina were 87.55 % and 16.80 % at an initial sanility concentration of 15 and 25, respectively. In conclusion, Avicennia marina has a potential to be used in bio-desalination in a reed bed system reactor.
