PROCEDE D'OZONISATION DESTINE AU MAINTIEN DE LA VIE AQUATIQUE

OZONATION PROCESS FOR AQUATIC LIFE SUPPORT

Abrégé anglais

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.

Revendications

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.

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.
