This is an explanation of as Jow sand filter (SSF). The reason of change from SSF to ar apid sand filter (RSF) in Ja pan is discussed. The occurence of odor trouble in tap water is described. The difference of both treatments is described precisely. It is emphasized that the efficiency of land utilization of SSF is same as that of RSF. The mechanism of production process of the high water quality of water by SSF is explained on the standpoint of biological activity of algal and heterotrophic communities. The reason of occurence of filamentous algae in SSF is explained and the role of filamentous algae is evaluated. The ideal management of SSF is proposed on the standpoint of algal activity. The weak points in biological treatment are discussed. The conservation of water sources is emphasized for the safe and high quality tap water.
