Abstract

The most important feature of this process is that no water is dumped as in existing fish raising facilities and the operator completely controls the water quality. All the water is continually recirculated and is continually sterilized by the use of OZONE gas in the O3 state. The OZONE gas in the water that is left over is then changed back to oxygen by the use of ultraviolet rays in the 254 nanometer range and is pumped into the water tank containing the aquatic life. By changing the OZONE back to oxygen the need for large air pumps is eliminated, thus stopping the harmful practice of pumping 78%
nitrogen into the water.
Twice as many fish, for example, can be raised one and one half times quicker with no dumping of fish wastes and with one half the utility bill. Fish health is controllable as well.

Description

215~221 lltle: Ozonation Process For Aquatic Life Support I.,~entor: Krissttovvv ~eading: SPECIFICATIONS

This invention is a process for oxidizing the waste water produce~ by raising fish and all other forms of aquatic life indoors, and also in outdoor ponds and tanks. All viruses, dlseases, parasites, etc., can be controlled using the ozone gas, thus removing all the usual stress factors from the fish raising. our swiftly depleting fish stocks around the world created the need for a more efficient, more environmentally friendly way to raise fish indoors for food, for testing, or for stocking. Since ozone is the most powerful oxidant known, thus this new process.
In figure 1. the drawing shows the basic outline of the machinery in total. The catwalk #7. allows easy access to both tanks. Water from the bio-filter #1. flows by gravity to the ozonation equipment #2. where the water is mixed with ozone in the baffle tanks. The ozone kills all bacteria, viruses and fungi and all potential algae blooms. This water is then pumped up into the ultra violet destruct system #3.
where the excess ozone is changed back to oxygen before being dumped into the fish tanks #4 (for example). These tanks may be any si2e or shape in order to accommodate all forms of aquatic life. Lobster tanks, for example, may be long, flat and only 12 inches deep. The water from the tanks, #4., flows by gravity out the bottom into the sump tank #5. and overflows into the mechanical filter #6.. The mechanical filter takes out the aquatic waste in a damp solid form to be dried, bagged and sold. The cleaned water then flows by gravity into the bio-filter tank #1. where the action of the bio-media removes nitrites and ammonias, and the process begins again.
Processes used currently for the indoor raising of aquatic life have no provision or method for removing the viruses, diseases, bacteria or other stress factors that result in poor fish health and high mortality rates. Fish farms also use large air blowers to inject air into the fish tanks in an effort to get oxygen into the water for the fish. In doing this, close to 78% nitrogen is injected at the same time which is detrimental to fish health and growth rates. Using ozone these above two problems are totally eliminated. New en~Tironmental laws prohibit the dumpin~3 of fish waste (mar1u into streams, rivers, lakes, and soon, dumpinc3 into duc30ut;
will also be prohibited. The use of a mechanical filter solv~:
these problems and also allows the bio-filter to do w~at it was designed to do instead of beincJ a mechanlcal filtl?r.

Claims

CLAIMS:

1. The embodiment of the invention is the integrated use of the ozone and ultraviolet which solves the problems associated with raising dense aquatic life populations indoors. This process is also a 'green' process which complies will all new environmental laws in place and new ones soon to come.

2. By removing disease stress factors using ozone the fish tanks can be loaded with more pounds of fish (for example) per cubic foot of water and these fish eat more pounds of food due to oxygen rich water and in turn grow at a faster rate.

3. The ozone eliminates the use of all chemicals which translates into faster growth rates and healthier fish. Because of the adjustability of the ozone equipment, the fish farm owner has complete control over water quality and oxygen content; and weather, if the tanks are indoors.
