Abstract
Removal characteristics various water Parameters of Lake Kasumigaura, which was very eutrophicated, were determined by biological oxidation treatment (biologicaltreatment packed with honey comb tube) during the period from 1985 to 1988.
Turbidity, odor, total-algae, blue green algaMicroysriscould be effectively removed and average removal of the parameters was over 60% during the investigated periods. There was a reverse correlation between the number of smaller animals in the bio-film and water temperature, while the numbers were closely correlated with the removal of turbidity.
