Abstract

This study focusses on a measure to remove dissolved phosphorus and nitrogen from river water flowing into reservoirs. Aquatic treatment is a typical such method, but has the shortcoming that the facilities covering a large area are required. In this paper, we use filamentous algae communities, which have a high multiplication rate compared with other freshwater plants and which can be applied throughout the entire year. We aim to resolve the problem by installing artificial beds for cultivating such filamentous algae communities at places around reservoirs that have little value in terms of other uses. We present specific propositions for facility structure and site selection and clarify the problems expected in putting these proposition into practice.
