The water quality in Lake Biwa is constantly affected same levels of concentrations in COD, T-N, T-P, but algae bloom or red tide is practically an annual occurrence. So, it is offen inadeguate for a source of water supply. Therefore it is necessary to make improvement to the water purification capacity of the main tributary into Lake Biwa, to augment past water quality preservation meseaurs.
This report describes the results of field experiments in water purification using aquatic plants. The water purification mechanism using aquatic plants was analyzed, and the optimum conditions for nutrients removal were determined.
The data generated by this study will he utilized for the design and operation of river water purification facilities.
