Unusual growth of undesirable algae caused by eutrophication has brought water quality problems of water bloom or odor in some reservoirs. Countermeasures against the phenomenon are to understand a growth mechanism of the algae and to prevent undesirable floating algae from rapid increase.
The water purification system proposed in this paper provides an environment to grow desirable algae, filamentous algae, which works to remove T-P and T-N from the river pouring into thereservoir and inorganics from the reservoir surface, resulting that increase of undesirable floating algae is to be prevented in the reservoir. Besides the system works to remove undesirable algae and oder from the discharge flow.
Explained and reported in this paper are on characteristics of the water purification system using filamentous algae and field experiments confirming the system to be effective for reservoir water purification.
