Membrane-based recirculating aquaculture system: Opportunities and challenges in 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 (RAS) 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 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 RAS (MRAS) for shrimp farming are analyzed.

Automated summary

Membrane technology has great opportunities and challenges in the application of recirculating aquaculture systems. Microfiltration, ultrafiltration, or membrane bioreactors can improve water quality and reduce water consumption. In addition, membrane-based systems also have promising prospects in shrimp farming.
