Improvements in the Ozonisation or Oxidation of Water and
Substances Mixed with Liquids.
EMILE ANDREOLI, Journalist, The Acacias, 147, Cold Harbour Lane, Camber-
well, S.E., do hereby declare the nature of this invention to be as follows:-
The object of this invention is an improvement in the ozonisation or oxidation
of liquids or of substances mixed with liquids, such as pulverulent matters or
matters in a fine state of division, so as to obtain a more efficient oxidation in
less time, at a lesser cost and in a more efficient manner than by the ordinary
methods.
In carrying out this invention, instead of oxidising a liquid by ozonised air or
oxygen blown or aspirated through it, in a tank or other recipient, I obtain a
complete oxidation of the liquid mass in the body itself and the delivery pipe of
a rotary or centrifugal pump, where, ozone is driven by suction from the ozoniser.
Thus, the ozone is intimately in contact with the liquids and with every particle
of the substances therein to be oxidised, which under constant ozonisation are
conveyed to a tank, wherefrom they may be taken back to the ozonising pump
and treated once or several times more, according to the requirements.
This mode of saturating a liquid or the substances with which it is mixed, by
ozone can be utilized for different commercial applications; I will give as an
illustration of the process, the purification and sterilization, by ozone, of con-
taminated water.
The quantity of ozone admitted into the body of the pump and its delivery
pipe is small comparatively with the volume of water, but this stream of ozone
is constant and the ozone, violently beaten with water impinges on each of its
molecules and acts energetically on the organic matters and micro-organisms
with which it is contaminated and destroys them.
In this way, the maximum of oxidation is produced with much less ozone, less
mechanical and electrical energy, than in the usual methods of sterilization of
water or of oxidation of liquids and substances mixed with liquids.

page_text: this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to the improvement in the ozonisation or oxidation of
substances either in solution or in suspension in a liquid, or pulverulent matters,
or matters in a fine state of division, so as to obtain a more efficient oxidation in
less time, at less cost, and in a more rapid manner than by the ordinary methods.
In carrying out this invention, instead of oxidising a liquid in a tank or other
convenient recipient, through or from which ozonised air is blown or aspirated, I
obtain a much more complete oxidation by introducing the ozonised air and the
liquid, into the body and delivery pipe of a centrifugal or rotary pump, or the
like, where the gas and the liquid are well mixed.
Thus, the ozone is in intimate contact with the water, or other liquid, and with
every particle of the substances to be oxidised therein, and the liquid flows into a
recipient wherefrom, if necessary, .e. if the oxidation is not complete yet it may
be taken back to the pump and ozonised once, or several times more, according
to the requirements.
This mode of ozonising a liquid, or the substances with which it is mixed, can
be utilized for different commercial applications, such, for instance, the steriliza-
tion of impure drinkable water.
The advantage of this ozonisation, is that the percentage of the ozonised air
admitted in the body of a pump and in its delivery pipe can be calculated so
that there is no waste of ozone escaping in the air. The quantity of ozone which
enters the pump may be small when compared with the volume of the liquid,
but the stream of ozone which is driven into the pump is constant, and the
oxidising gas violently beaten with water impinges on each of its molecules, acts
energetically on the micro-organisms with which water is contaminated, and
destroys them.
In this way, the maximum of oxidation is produced with much less ozone and
less mechanical and electrical energy than in the existing methods.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
The above described improvement in the ozonisation or oxidation of liquids or
of substances mixed with liquids by ozonised air in a centrifugal or rotary pump,
or the like, where, by agitation, their intimate contact.is effected.
