Abstract
A water treating method is disclosed. Water stored in a container is circulated through an external passageway and subjected to ultraviolet radiation and biological oxidation treatment, whereupon the growth of undesired aquatic chlorophyceae and microorganisms is inhibited and at the same time, organic matter is decomposed and removed, thereby maintaining a low COD level and clarifying water in the container. This method is particularly useful for keeping water in a container clean.
