Abstract: From a water medium, a harvester recovers algae useful as animal feed. The harvester has a preferably endless, movable belt screen. A coating device puts a first coating of long fibers (such as glass fiber or asbestos mixed with paper fiber) onto one side of the belt screen. A container of algae in water discharges onto the first coating permitting much of the water to pass through it and the belt screen but holding back the algae largely as a second coating on the fibers. A second screen having finer openings than the first screen is disposed against the second coating. This second screen has openings large enough to pass the algae but small enough to hold back the fibers. A suction is applied to the second screen causing the algae and entrained water to move therethrough. Concurrently, a washer directs a stream through the first screen and through the first coating and so washes off the second coating of algae, the fine screen holding the fibers behind.
