The idea is to combine two flow-through raceways into a D-ended type system with flow velocity created by the white water aeration and water mover device, used with the IPRS In-Pond Raceway System. The fish would be grown in the first raceway, at least twice normal density, and the solids can be settled in the second raceway. In-flowing water will enter the fish culture unit and exit after passing through the solids settlement raceway. The purpose is to improve fish health and yields as well as reduce environmental impact by maintaining high DO levels with aeration and remove as much solid waste as possible from the effluent.
The white water unit is shown on my short YouTube video of the IPRS for introducing the concept: https://www.youtube.com/watch?v=3-Bcy79vpJ8
