Abstract
In this study, a new method has been developed for the direct removal of algae from eutrophic water. A pair of electrodes consisted of copper (or aluminum) plate cathode and aluminum plate anode was set in an eutrophic water suspended algae, and then direct current was applied. The applied current and concentration of algae were varied in the range of 10-180 mA and 1.00X108-9.96X108cells·ml-1, respectively.
As algae have negative charge in water, they migrated to the anode and then adhered on its surface. The adhered algae were easily detached from the anode and removed from the water at high efficiency. The accumulation rate of algae on the surface of anode was increased with increasing applied electric current and initial concentration of algae.
