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.
