  • Patent number: 8997694
    Abstract: A system and method for removal of phosphates from a closed loop estuarine or marine recirculating aquaculture system (RAS), involving denitrification in the presence of a media substrate for: 1) anaerobic nitrate, nitrite and ammonia removal and 2) sequestering of excess phosphate in the RAS. Phosphate is precipitated in or on the denitrifying biofilm formed on the media substrate as phosphate salts. The phosphate salt-containing media substrate can be removed from the RAS, the phosphates can be removed, and both the substrate and the phosphates can be reused or recycled.
