FIELD: chemistry; water purification.
SUBSTANCE: method provides algolisation of water reservoir with adding suspended green microalgae Chlorella vulgaris IGF № C-111. It follows collecting cyanobacteriae after log phase that is linear growth phase in the morning from 4 o'clock till 6 o'clock. It is combined with artificial aeration: biological in winter, freezing over, by clearing out the ice from snow 1/3 to 50% of reservoir area not damaging ice cover, hydromechanical in winter without freezing over and in spring every 3-4 weeks. Hydromechanical aeration is applied at least twice.
EFFECT: prevented bloom ensured with lowered concentration of cyanobacteriae.
