Sustainable Water Solutions to Increase Yields and Improve Quality in Recirculating Aquaculture Systems

A White Paper by Evoqua Water Technologies


Singapore’s 30-by-30 goals have provided an impetus for the evolution of fish farms to increase local food production. Recirculating aquaculture systems (RAS) are the resulting product of this evolution. Although RAS has begun to be implemented in fish farms, water quality degradation that stems from water recycling is still a major concern. We aim to address these concerns and to provide solutions through our products.


To achieve the objective of increasing production in local fish farms, fish farms nowadays evolve rapidly from labor-demanding and inefficient traditional fish farms to high-tech modern mass-production fish farms. Due to this shift, there will be a new opportunity for us, as a water treatment company, to take our part in this technology shift and generate profits in this new vertical market.

Currently, there are more than 100 licensed fish farms in Singapore, the majority of them are small farms with low technology investment. These said fish farms are classified as traditional fish farms. However, there are some large farms using a more advanced way of fish farming by utilizing RAS.

RAS is a method for farming aquatic organisms by reusing the water that is needed for production. This method has been successfully used to farm many aquatic species such as fish, shrimp, abalone, and shellfish. RAS possess biological and mechanical filtration systems that recycle and treat used water from farming aquatic animals. Fill out the form to continue reading.
