In order to reduce the influence of algae on the conventional treatment process of the water plant, the electro-flotation process was used to test the Cushions raw water of a lake-type reservoir.After raw water with cyanobacteria as the dominant algae is treated by the best electro-flotation process, the average removal rate of algal density can reach 99.1%.The effects of current density, Plush residence time, and electrode spacing on the algal removal efficiency of the electro-floating process were investigated by orthogonal experiments.

The order of influence was current density > residence time > electrode spacing.Considering economics, the optimal process conditions were as follows: the current density was 5 mA/cm2, the dwell time was 6 min, and electrode spacing was 10 mm.
