A Facility Composed by Oyster Shell Filters for Purifying Contaminated Water in Closed Water Area

Various technologies are developed about the improvement of seawater property in the closed water such as the inner bay and lakes and marshes. The seawater exchange tends to stagnate in the closed water because flow is small. Therefore, even if the effective technology to the improvement of seawater property is set up, the effect becomes limited. Then, flow is cased by using the energy of the small-scale wind waves generated in the closed water, and it proposes effective use of the water quality purification. Additionally, the hydraulic model experiments and the numerical simulation of the facilities are executed, and the effectiveness is conformed.
