Abstract
The main objective of this study was to evaluate the current condition of harbor sediments and to estimate biochemical methane potentials from the harbor sediments. Sediment samples were collected from 10 different sampling sites. Ignition loss, elemental analyses, X-ray diffraction(XRD), X-ray fluorescence(XRF) tests were conducted to determine characteristics of the sediment. All sediments had similar elemental compositions and ignition loss were 8~10%. From the conventional BMP tests for 5 samples, cumulative methane production ranged from 11.9~15.5mL methane/(g of volatile solids), which were significantly lower than that for foods and paper. However, methane production rates for sediments were 5 to 20 times faster than those for foods and paper.
