Description

~92~
This invention relates to a method for enriching water
with oxygen according to the preamble to the main claim, and to an
apparatus for the implementation of this method.
In many agricultural and horticultural operations, and in
fish-breeding installations, water needed to operate -the equipment
is taken out of the ground and is fed to the plants or animals.
Experience has shown that this water is relatively low in oxygen
and there have been numerous proposals for the general enrichment
of water with oxygen. For example, it is known from German A 27
05 2~3 or French A 23 90 989 to insert, into a water-supply line,
a suction nozzle having a suction connection in the form of an air-
suction-connection, so tha-t, when the unit is in operation, air is
drawn from the environment and is mixed with the water.
However, these known methods fail to provide a high or
satisfactory degree of oxygen enrichment.
On the other hand, it is known that geologically-active
oxygen promotes the well-being of mankind and has been found
beneficial for various diseases. Biologically-active oxygen is
found in health resorts, at the seaside and in the mountains, where
it is Eormed under normal weather conditions.
It is the purpose of the invention to achieve high oxygen
enrichment of wa-ter effectively with very simple means.
According to the invention, air drawn in by a suction
nozzle is passed through the field of influence of an ion-generator
and thus contains a large proportion of negative ions. This
ionized air brings about unusually high oxygen enrichment of the
water in the vicinity of the suction-nozzle. The mixture of water
and ionized-air is not released at this time, but is passed through
a pipe-coil to the release location, so that intensive mixing of
ionized air and watar is maintained over a long period of time, to

wit over the entire length of the said pipe-coil; this ensures that
the oxygen enters the water.
In addition to increasing the amount of oxygen in the
water, which is of importance in rearing plants and animals, the
method and apparatus according -to the invention, as a result of
this large amount of oxygen, destroys the bacteria in the water of
makes the water or makes the water less susceptible to bacteria.
An example of embodiment of the invention is explalned
hereinafter, in conjunction with the drawing attached hereto.
In the said drawing, 1 is a water reservoir, -the water of
which must be replenished, or which serves as a storage-basin, the
water to be introduced into the said reservoir being required to
contain a large amount oE oxygen.
Water is supplied through a line 2 into which a so-called
suction-nozzle 3 is inserted. 4 is the suction-connection for
suction-nozzle 3, air-inlet opening 5 of this connection opening
freely above an ion-generator 6. In the example of embodiment
illustrated, two ion-generators 6, 7 are provided. These exhibit
concavely arched front plates 8, 9, at the lowest points of which
are arranged the emission-needles of the said ion-generators. The
said~front plates are at a distance from each other such that the
air drawn in by air-inlet opening 5 passes through the gap between
front plates 8, 9, as shown by arrow F in the drawing.
Connected to suction nozzle 3 is a pipe-coiI 10 which
opens into reservoir 1 and cons-titutes discharge point llo The
device described, consisting of suction nozzle 3, ion-generators
6 and 7, and pipe-coil 10 is arranged in a cylindrical connection
12 comprising passages 14. in the upper part o the said
cylindrical connection, these passages allow air to enter; in the
lower part they promote the exchange of water.

z~
When ion-generators 6 and 7 are put into operatlon, they
produce, in -the vicinity of front plates 8 and 9, air with a high
proportion of negatively charged ions. As soon as water is
supplied through line 2, suc-tlon nozzle 3 draws air through suction
connection 4, this air containing a large proportion of negative
ions, creating a mixture of ionized air and water. The mixture now
en-ters pipe-coil 10 and flows, over a relatively long path, to
discharge point 11, providing ample time for the water to absorb
oxygen from the ionized air.
The arrangement of ion-generators 6, 7 in front oE
suction-connection 4 not only ensures the desired oxygen-
enrichment of the water, but also destroys bacteria both in the air
and in the water. The water entering the reservoir thus contains
a large amount of oxygen and has a high degree of purity.
In short, the method and apparatus according to the
invention enriches the water with biologically active oxygen, thus
improving purifying ability, i.e. the water molecules are capable
of polarizing the particles of dirt and of killing bacteria.
Ground-water low in oxygen is converted into water which contains
a large proportion of biologically active oxygen, so that organisms
treated therewith improve with respect to quality, strength, growth
and fruitfulness. Tissue tonicity is increased (this is known in
medicine as "turgor"). Thls improves micrometabolism and leads to
improved absorption of magnesium and iron.
'
Tests carried out in a greenhouse showed that the use of
water enriched with biologically active oxygen makes it possible
to obtain stronger, more healthy plants, tha-t mould-diseases and
bacteriological infestation no longer occur, and that there is also
a decline in the number of harmful insects. Moreover, fruit thus
grown keeps fresh for longer periods of time.
