In order to enhance pore ratio and durability, media-type algal bloom inhibition chemical was manufactured from powder form. The results showed that the media increased effective contact time between the water to be treated and the effective components in the chemical, and thus, chemical dose and sludge production were significantly reduced.

At research, the river's water which the sewage treatment facility will ask growth suppression the algae in the artificial rivers which it is using or it researched the method for the removal of the algae which grew. At results, when 60ppm of Chlorine was put in, the possibility of getting the result where 90% chlorophyll-a was removed and LC50 was 0.8ppm. The algae did not create even after 20days by which uses prevent agent of creation of the algae. Controlling the chlorine almost there was not an extinction effect of the algae which was already in large quantities multiplied, with in the effect against an water ecosystem widely known it is not. The prevent agent could inhibit creation of the algae, but it was judged with the fact that the methods are directly applied to the field must be researched continuously.
