PATENT OFFICE.
PAUL KESTNEB, OF BOULOGNE-SUR-SEINE, FRANCE.
(No Drawing.
' To all whom it may concern:
Be it known that I PAUL Knsrnnn, engineer, citizen of the l rench'Republic, residing at Boulog'ne-sur-Seine, Department 6 of the Seine, in France, and having P. 0. address 113 Boulevard de Strasbourg, in the said city, have invented certain new and useful Improvements in Methods of Treating Water; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use they same.
This invention consists in improved metallic media for the fixation of the oxygen of water in apparatus for abstracting gases from li uids. g The xation of the oxygen dimolved in water is brought about in apparatus for ab- 2 stracting gases from liquids by the chemical combination of this oxygen with iron filings and turnings, and is represented by the to lowing chemical reactions:
2Fe+30=Fe,O,. This oxidation is not immediate but reand quires a certain time to give aquantitative res In. accordance with the invention a small un'rnon or rnmrme wn'rnn.
application lied April 16, 1921. Serial No. 461,925.
quantity of manganese is added to the iron.
he manganese acts as a catalyst in the oxidation and combines instantaneously with the oxygen, yielding oxide of iron and protoxide of manganese, MnO, capable of oxidizing in turn into dioxide and sesquioxide, which can be reduced again by the iron. The successive reactions which are brought about are as follows:
g fii fga 'iggb kxidatlon of the manganese.
Reduction of the oxidized man see and ggfgn gfi gfig o! the iron to the state iil protoxfllnor+3Fe=Fe o4+4Mno f g 'gfgggggma figfigg iiiiaoii 25%;: oxidized manganese lzpggiiagsglgpdgi the iron to the state In0+0-=)l.n0, )Oxidatlon oi the protcxide of manganese into 3MnQ+0-Mu;0 dloxnieand saline oxide.
All these reactions taking place in the water likewise take place between the same oxides in a hydrated state, and constitute a closed cycle, the protoxide of manganese absorbing oxygen continuously and giving it up to the iron until the iron is completely 65 saturated.
The proportion of manganese most favourable for'the catalysis is over 5% of the weight of the metal and below 6% of the weight of the iron. The speed of reaction [0 is proportional to the quantity of man, ganese employed and inversely proportional to the quantity of-carbon in t e metal.
Claim:
A method of treating water to de- (8 oxidize it, employing iron or steel filings or turning's containing from 5 to 6 per cent of manganese, the manganese acting as a catalyst'in the oxidationof the iron and increasing considerabl the speed of the reaction which takes p 00.
