METHOD FOR CONTROLLING ALGAL BLOOM

摘要

The invention relates to a method for controlling algal bloom, according to which cyanobacteria distributed throughout the water are isolated and are agglutinated and sedimented by the dosing of an acidic, cationic silica sol. The accretion of SiO2 particles on the bacterial surface weighs down the cyanobacteria and they sink to the bottom, where photosynthetic growth is inhibited as a result of light deprivation.
