PROVISIONAL SPECIFICATION.
A New Compound or Mixture for Purifying Sewage and Foul Water
or Liquid.
I, GEORGE WHALLEY of Chorley in the County of Lancaster, Clerk, do
hereby declare the nature of my said invention to be as follows:-
This invention relates to a new compound or mixture for purifying sewage and
foul water or liquid, and is designed to precipitate organic or albuminoid matter
contained therein as quickly as possible from a soluble compound or mixture of
metallic oxides in the highest state of oxidation, which consists of boxite or other
aluminous compounds of suitable weight in conjunction with ferric oxide obtained as
a waste product in the extraction of copper ores of poor or low quality, or other
sources, such as, waste obtained in the manufacture of sulphuric acid. This
compound or mixture is treated with a quantity of either sulphuric or hydrochloric
acid, and if necessary a small quantity of nitric acid may be added; the whole
being mixed in an earthenware vessel, which may be heated or otherwise. This
mixture will form a solid body composed of alumina and ferric sulphate.

or Liquid.
I, GEORGE WHALLEY of Chorley in the County of Lancaster, Clerk, do
hereby declare the nature of my said invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :—
.
This
This invention relates to a new compound or mixture for purifying sewage and
foul water or liquid, and is designed to precipitate organic or albuminoid matter
contained therein as quickly as possible from a soluble compound or mixture of
metallic oxides in the highest state of oxidation, which consists of bauxite or other
aluminous compounds of suitable weight in conjunction with ferric oxide obtained
as a waste product in the extraction of copper ores of poor or low quality, or other
sources, such as, waste obtained in the manufacture of sulphuric acid.
compound or mixture is heated with a quantity of either sulphuric or hydrochloric
acid, and if necessary a small quantity of nitric acid may be added; the whole
being mixed in an earthenware vessel, which may be heated or otherwise. This
mixture will form a solid body composed of sulphate of alumina and ferric sulphate.
In case of hydrochloric acid being used this mixture will form chloride of alumina
and ferric chloride. These mixtures are employed in proportion to the quality or
nature of the sewage and foul water or liquid to be treated.
The proportions of this new compound or mixture are as follows:—

page_text: Having now particularly described and ascertained the nature of my said invene
tion and in what manner the same is to be performed, I declare that what I
claim is :-
For purifying sewage and foul water or liquid the use of the before mentioned
mixtures consisting of bauxite or other aluminous compounds and ferric oxide with
sulphuric or hydrochloric acid as the case may be, substantially as described.
