| When the europhication in a closed sea area is progressed by the increase in inflow and accumulated pollution loads the proliferation of algae occurs and it causes seawater pollution. It is necessary to maintain that the seawater is clean for the sustainable development. One of methods is the seawater purification system built in quays using purification functions of microorganisms and the tidal energy. It is shown that this quay can be utilized in order to decrease Chemical Oxygen Demand (COD) using the tidal energy and microorganisms' functions of purifying the seawater. The initial COD is almost 8 by putting sugar adequately in seawater and mixing. The changing process of COD is checked by measuring COD (JIS K 0102:Japanese Industrial Standards). In the case of seawater purification system COD is getting smaller and it is found that this system can reduce COD in seawater. |
