Measures for lake water quality conservation using filamentous algae.

Abnormal growth of undesirable algae caused by eutrophication has brought water quality problems of algae bloom or musty odor in some lakes.Measures against the phenomenon are to prevent undesirable floating algae from rapid increase.The lake water quality conservation proposed in this paper provides an environment to grow desirable algae, filamentous algae, which works to remove PO4-P and T-P from the river pouring into the lake and the lake surface, resulting that increase of undesirable floating algae is to be prevented in the lake.Besides the system works to remove undesirable algae and musty oder from the discharge flow.Explained and reported in this paper are on characteristics of the lake water quality conservation using filamentous algae and field experiments confirming the measure to be effective for lake water purification.
