Spray bars work on timers to remove foam from the system which contains submicron particles.
The Aqua 2100 system utilizes air to circulate water to the culture tank from the clarifier. The system is designed to provide two “opposing flows” of water, created by compressed air being introduced at the base of each side of the tank. As the air rises through the water it not only provides oxygen but also creates two opposing circulating flows. This circular pattern enables solids to be gently drawn into the outflow ports located at the bottom on both sides of the tank and passed through, intact to the clarifier.

This unique (Patented) “Opposing Flow” technology also creates a continual current in the culture tank. After the biofilter, the purified water is evenly distributed back into the culture tank, entering from both sides of the tank causing the fish to align themselves in the current, constantly swimming “ upstream” facing either side of the 40’ long tank. With this constant swimming motion the fish can metabolize the high protein feed into flesh which will them a higher yield as compared to fish grown in circular aquaculture tanks.

Opposing Flows Technology Air Diffusers oxygenating the water.

Oxygen is injected into the system at three points. One is in the biofilter area where there is 48 feet of Opposing Flows air diffusers. The second is in the culture tank itself where there is 180 feet of Opposing Flows air diffusers. The third is through the airlift water return system. Only one blower is required to handle all three of these processes and can also operate multiple tanks, although a backup is recommended. With this system we have densities of .85 pounds per gallon regularly.

Clarifier section of the filter unit. Water passes through here at a rate of 270 gallons per minute.
There are 5 stages of solids removal in these filters.
The aquaculture tank is filtered 1.7 times per hour.
