Abstract
A continuous process for efficiently harvesting microalgae from aqueous systems is described herein. The method and apparatus of the present invention allows continuous harvesting of algae from a variety of source waters including saltwater, brackish water, fresh water, and treated wastewater. High concentration factors are achievable and the system produces a deflocculated product that is readily processed for biofuel or pharmaceutical applications. The process of the present invention does not add contaminants that can limit the downstream usage possibilities for the algae concentrate produced. The effluent water from the process is suitable for conventional discharge or recycling to the growth system. The process of the present invention is inexpensive, scalable, and generates useful effluent water and algae concentrate as products.
