• Slow Sand Filtration (SSF) is a biolofical system to purify tap water. In this study, dissolced oxygen concentration and its diurnal changes were measured at three different production rate was almost the same in there three different SSF plants. Different tratments of floating algae were done in these SSF plants. The daily respiration rate at the Sodeyama plant was the lowest rate. The floating algae were effectively removed at this plant. Therefore, oxygen consumption by floating algae became minimal. The removal of floating algae reduces oxygen depression, even in the nighttime. Hence, it is effective remove of floating algae to make desirable filtrate water.
