저서생물의 환경생태학적 특성을 이용한 완속 모래여과지의 조류제거 = ORIGINAL ARTICLES : Removal of Algae in a Slow Sand Filter using Ecological Property of Macrobenthos(Pomacea canaliculata)

다국어 초록 (Multilingual Abstract)

After identifying species by collecting the suspended and attached algae mat inhabiting in the slow sand filter, Spirogyra sp, Mougeotia sp. Was dominant species. A result of observing the life mode of apple snail for a month after introducing into the slow sand filter, apple snail eggs were discovered on the filter walls 2 weeks after introducing, 4 weeks later lots of eggs were observer all of the slow sand filter walls, it means there is no problem for apple snail to live in the slow sand filter. The observation result for algae removal potential by introduced apple snail after 2 months later, slow sand filter where apple snail were introduced, a few algal mat were observed, On the other hand, no introduced apple snail into the slow sand filter, lots of suspended algal mats were formed in the water and attached algal mats on the sand surface as well, these algal mat induced much of operating problems.
