Complete Specification Accepted, 28th Sept., 1888
We, EUGENE HErmite, Edward JAMES PATERSON and CHARLES FRIEND COOPER
all of European Works Pownall Road, Dalston in the County of Middlesex,
Engineers, do hereby declare the nature of this invention to be as follows:-
This invention relates to a process for disinfecting impure liquids such as sewage,
discharge from soil pipes, bilge water or stagnant water, or generally any liquid
holding organic impurities in suspension or solution. For this purpose we mix with
the liquid to be disinfected certain chlorides or solutions of chlorides, such as
magnesium or calcium chloride, or sodium chloride, the last of which may in many
cases be most cheaply and conveniently applied by using sea water or the mother
liquors obtained in the evaporation processes for producing salt. We then pass the
liquid mixed with the chloride or with several of the chlorides, preferably in thin
streams or sheets between electrodes which are respectively connected to the terminals of a
dynamo electric machine or other generator of electricity, and thus an electrical current
is made to traverse the liquid as it passes the electrodes. The effect of this is a
temporary decomposition of the chloride which causes an action on the impurities such
as renders them innocuous.

A Process for Disinfecting Impure Liquids.
We, EUGENE HERMITE, EDWARD JAMES PATERSON, and CHARLES FRIEND COOPER,
all of European Works, Pownall Road, Dalston, in the County of Middlesex,
Engineers, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following stateinent :-
This invention relates to a process for disinfecting impure liquids such as sewage,
discharge from soil pipes, bilge water or stagnant water, or generally any liquid
holding organic impurities in suspension or solution. For this purpose, we mix with
the liquid to be disinfected certain chlorides or solutions of chlorides, such as

causes an action on the impurities such as renders them innocuous.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, we declare that what we
claim is :-
The herein described process for disinfecting impure liquids by adding to them
chlorides and subjecting the mixture to electrolytic action, substantially as described.
