Aquaneering Denitrification System
Enter the denitrification system. Denitrification systems have been in use for several decades, primarily in wastewater treatment, but have not been traditionally used in aquaculture and aquatic filtration systems.
Dallas Weaver, Ph.D. and the Aquaneering
production team testing the denitrification system
The denitrification system currently being developed by Aquaneering reduces nitrate to nitrogen gas and then uses an aerobic fluidized bed to oxidize any residuals from the anaerobic denitrification reaction. This system will be used to process and recycle the high nitrate wastewater for a striped bass hatchery in Ensenada, Mexico. The system will support brood stock and fingerlings for production, which will be released to pens in the Pacific at a certain age and size for grow-out.
The unique design is a collaboration between Dallas Weaver, Ph.D., of Scientific Hatcheries, and Mark Francis of Aquaneering. The system will process 60 to 120 tons of water per day, providing nitrate-free return water and eliminating an equal volume of total water demand.

The Ensenada hatchery will have recirculating water and zero discharge in an environment with a very limited water supply. The end result: protecting precious resources and supporting fish hatcheries through technological innovation. |
