We WILLIAM CAMERON SILLÁR of St James's Lodge: Kidbrooke Park Road
Blackheath in the County of Kent Gentleman and the NATIVE GUANO COMPANY
LIMITED of No 29 New Bridge Street in the City of London Manufacturers of
Manure do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE TREATMENT OF SEWAGE AND OTHER LIQUID OR SEMI LIQUID PUTRESCENT OR
PUTRESCIBLE MATTERS to be as follows:-
"
Our invention relates to those processes for the treatment of sewage and other
liquid or semi liquid putrescent or putrescible matters in which the said liquids are
purified or precipitation of the solid matters in suspension and solution therein is
produced by the addition thereto of cheinical solutions or liquid mixtures and our
said Invention consists in adding such solutions or mixtures in a heated state to
the liquids to be treated whereby the chemical action of the said solutions or
mixtures on the sewage or other liquid under treatment is expedited.
The solutions or mixtures herein before referred to may be heated by diluting
them with hot water or by blowing steam into them or by other convenient means.
The temperature to which we prefer to beat the said solutions or mixtures is from
about ninety degrees to about one hundred and twenty degrees Fahrenheit we
however do not limit ourselves to this range of. temperature as the said solutions
or mixtures may advantageously be used at higher or lower temperatures.

We WILLIAM CAMERON SILLAR of St James's Lodge Kidbrooke Park Road
Blackheath in the County of Kent Gentleman and the NATIVE GUANO COMPANY
LIMITED of N° 29 New Bridge Street in the City of London Manufacturers of
Manure 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 statement:-
Our invention relates to those processes for the treatment of sewage and other
liquid or semi liquid putrescent or putrescible matters in which the said liquids are
purified or precipitation of the solid matters in suspension and solution therein is
produced by the addition thereto of solutions of salts of aluminium salts of iron
salts of manganese or salts of copper or solutions of salts of other heavy metals or
true earths (excluding the so called alkaline earths) in which processes liquid
mixtures consisting of clay or earth and carbon or carbonaceous matter and water
are in some cases also added to the liquids to be treated and our said Invention
consists in adding such solutions or such mixtures or such solutions and mixtures
in a heated state to the liquids to be treated whereby the chemical action of the
said solutions on the sewage or other liquid under treatment is expedited.
The solutions and mixtures hereinbefore referred to may be heated by preparing
them with hot water or by diluting them with hot water or by blowing steam into
them or by other convenient means. The said solutions or mixtures may be
advantageously used at any temperature higher than that of the sewage or other
matter to be treated. Where the said solutions or mixtures can be conveniently
beated to boiling point we prefer that temperature.
In cases, where solutions of the kind hereinbefore described or referred to and
mixtures of the kind herein before described or referred to are both to be added to
the sewage or other matter to be treated we prefer to use both the said solutions
and the said mixtures in a heated state but the solutions alone may be used in a
heated state and the mixtures at the ordinary temperature or the mixtures alone
may be used in a heated state and the solutions at the ordinary temperature..
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed we would observe
that we are aware that it has been proposed to use a boiling mixture of water and
quicklime and soda or black ash in the treatinent of sewage and we wish it to be
understood that we make no claim to the use of such a mixture in a heated state
or to the use of any mixture or solution in a heated state except the mixtures or
solutions herein before described or referred to but we declare that we claim as the

page_text: said invention of "Improvements in the treatment of sewage and other liquid or
semi liquid putrescent or putrescible matters
"
First The treatment of such matters by the addition thereto of solutions of salts
of heavy metals or true earths (excluding the so called alkaline earths) heated to
a temperature higher than that of the matters to be treated.
Secondly-The treatment of such matters by the addition thereto of liquid
mixtures consisting of clay or earth and carbon or carbonaceous matter and water
heated to a temperature higher than that of the matters to be treated in conjunction
with the treatment of the said matters with solutions of metallic or earthy salts.
