Membrane-based recirculating aquaculture system: Opportunities and challenges shrimp farming

Membrane applications in the aquaculture industry are continuously being developed for their effectiveness in removing various water contaminants such as suspended solids, toxic substances, pathogen microorganisms, and eutrophic compounds. The integration of membrane processes into a recirculating aquaculture system is believed to be able to achieve the sustainability of the aquaculture industry economically, environmentally, and socially. In the current review, the opportunities, and challenges of membrane application in recirculation aquaculture systems (RAS) are comprehensively discussed. The feasibility of microfiltration, ultrafiltration, or membrane bioreactor to maintain the quality of culture water and reduce water consumption is evaluated. Thereafter, the prospect and challenges of membrane-based recirculating aquaculture system (MRAS) for shrimp farming are analyzed. •One of the promising applications of membrane integration in RAS is shrimp farming.•Ultrafiltration can continuously remove pathogens with high rejection.•MBR application for RAS can certainly be used to remove nitrogen.•The biggest challenge in MRAS is the high cost of equipment and operations.
