PROVISIONAL SPECIFICATION.
Improvements in the Treatment of Water.
I, SYDNEY PITT, of Sutton, in the County of Surrey, Gentleman, do hereby
declare the nature of this invention (which has been communicated to me from
abroad by "Laboratoires Sauter Société Anonyme, Usine des Charmilles,
Geneva, Switzerland,) to be as follows:-
"
This invention consists in a new process of sterilizing water, which may be
easily used for the sterilization of drinking water, the same being applicable
without any special apparatus by merely throwing into the water, which may
be contained for instance in a drinking glass, two or more lozenges of a certain
composition which will be hereinafter described.
The process of sterilization consists in first producing in the water which is
to be sterilized, peroxide of hydrogen H₂O₂, by means of the reaction of an acia
alkaline salt with an alkaline peroxide, and to afterwards produce ozonized oxygen
gas O, by the addition of an alkaline permanganate Alk,Mn,O
When the sterilization is complete, the excess of peroxide of hydrogen H₂O,
and of ozone O, is destroyed by means of an addition of a hyposulphite Alk,S,O,,
whilst the remaining acid salt is neutralized by means of a bicarbonate AlkHCO,
the result is the formation of neutral salts of alkali and manganese with the acid
which has been used.
The several reactions occur simultaneously in the water which is to be sterilized,
in which there remains finally a solution of a combination of manganese and
alkaline salts in very small quantities and quite inoffensive.
In view of facilitating the use of the ingredients above specified the latter are
compressed to small lozenges or drops suitably proportioned in view of producing
the desired reactions.
The substances which are usually made use of in the said lozenges or drops
are the following ones:
--
Peroxide of sodium (Na₂O₂),
Disulphate of soda (NaHSO),

Geneva, Switzerland,) and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:--
This invention consists in a new process of sterilizing water, which may be

The process of sterilization- consists in first producing in the water which is
to be sterilized, peroxide of hydrogen H,O,, by means of the reaction of an acid
alkaline salt with an alkaline peroxide, and to afterwards produce ozonized oxygen
gas 0, by the addition of an alkaline permanganate Alk, Mn,08.
When the sterilization is complete, the excess of peroxide of hydrogen H₂O,
and of ozone O, is destroyed by means of an addition of a hyposulphite Alk,S,O.,
whilst the remaining acid salt is neutralized by means of a bicarbonate AlkĤČO,,
the result is the formation of neutral salts of alkali and manganese with the acid
which has been used.
The several reactions occur simultaneously in the water which is to be sterilized.
in which there remains finally a solution of a combination of manganese and
alkaline salts in very small quantities and quite inoffensive..
In view of facilitating the use of the ingredients above specified the latter are
compressed to small lozenges or drops suitably proportioned in view of producing
the desired reactions.

In order to facilitate the employment of the different ingredients they are
made up into compressed tablets properly dosed.
I usually employ:
Peroxide of sodium (Na₂O₂) 12 centigrammes.
Bisulphate of soda (NaHSO4) 75
دو
Permanganate of potash (KMn,Og) 35 milligrammes.
Hyposulphite of soda (Na,S,O) 12 centigrammes.
Bicarbonate of soda (NaHCO3) 3
for a thousand cubic-centimeters of water.
93
The proportions of the above mentioned ingredients are calculated so that the
water may be saturated with ozonized oxygen gas.
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:
1
1. The process of sterilizing water by mere chemical means characterized by
the combination of peroxide of hydrogen with ozonized oxygen (oxygen in the
nascent state), which is the natural purifying agent for water, the excess of the
oxydizing agents being neutralized after they have produced their sterilizing effect.
2. The treatment of water substantially in the manner described.
