The system consists of three circular concrete tanks were used for
fish culture. Dimensions of tanks are (5 m diameter x 1.25 m height),
(8 m diameter x 1.25 m height), and (10 m diameter x 1.25 m height).
The water volumes used in tanks were 25, 50, and 100 m³ respectively.
Each tank was provide to a particle trap in the center for water drain
waste solids, settleable solids flow under a plate, in a flow of water that
amounts to only 5 percent of the total flow leaving the center of the
tank. The larger flow (95 percent of the total) exits the tank through a
larger discharge strainer mounted at the top of the particle trap.
