Outline of Final Research Achievements

This study examines a water quality improving technology through the alleviation of anoxia via the activation of phytoplankton photosynthesis by LED irradiation under water. This technology can be proposed by focusing on the occurrence of anoxia in closed water body with advanced organic pollution due to the poor underwater lighting environment. In particular, laboratory experiments were conducted to consider the possibility of using algal photosynthesis with LEDs as their activating light source as a technology for improving water quality, particularly as a way to take aquatic environmental remediation measures in organically polluted waters where anoxic conditions could persist. The main focus of this present study was to relate the quality and intensity of irradiated light to the impact which the macroalgae and the long-term anoxic state have on its ability to improve water quality, including the level of dissolved oxygen.
