Abstract

The present invention is an improved method for removing microalgae from eutrophic water. The method comprises providing an Algae Settling Pond having an influent transfer means, that comprises a coagulant dosing means; and an effluent transfer means that comprises one or more upflow settlers, one or more floating perimeter baffles, and one or more surface launders. The settlers are fixedly positioned within the Pond and surrounded by the floating perimeter baffles, so that water is directed through said settlers to the surface launders to provide high level transfer for water out of the Pond. Eutrophic water is dosed with a cationic coagulant and then transferred to the Algae Settling Pond. The dosed water is directed into and up along the upflow settlers so that the algae is enable to agglomerate info floes and settle on a surface of the upflow settlers and slide down to the base of the Pond.
