Bioremediation of Salinity Problem by Using Collective Microorganisms in Semi-Aerobic Landfill
Publication: Geo-Congress 2023
ABSTRACT
The high saline content of the incineration ash of the semi-aerobic landfill is one of the major geoenvironmental problems in Japan. The traditional way to reduce the salinity by washing with fresh water is not conceivable due to the high cost. In this research, an innovative bioremediation idea has been applied to reduce the salinity of landfill ash. Collective microorganisms have been equipped in the laboratory for bioremediation. A semi-aerobic landfill simulator has been used in the laboratory. It has been noticed that the electrical conductivity has reduced around 68% after two weeks of bioremediation. The pH value also reduced and became almost neutral (7) after two weeks. The generated gas during the bioremediation has been analyzed by using gas chromatography. A small amount of gas containing chloride has been detected during the bioremediation, which is thought to be the reason for reducing salinity.
