Improvements in Deodorising or Disinfecting Rivers and Estuaries
or other Sewage or otherwise Polluted Collections of Water.
I, WILLIAM PATON BUCHAN of 21 Renfrew Street, Glasgow in the County of
Lanark, Sanitary and Ventilating Engineer, do hereby declare the nature of this
Invention to be as follows:-
This Invention has for its object to provide means for temporarily deodorising or
disinfecting rivers and estuaries or other sewage or otherwise polluted collections of
water. For this purpose a vessel such as a boat or steamer is made to move or sail
up and down or otherwise among the polluted water and when doing so there is
discharged from the sides or deck or other part or parts of the vessel or steamer a
deodorising or disinfecting liquid either upon or below the surface of the water in the
shape of spray or jets as for example is done by the water spray or jets from the tube
of a water cart for watering roads or streets; or disinfecting or deodorising gas or
gases may be ejected below the surface of the water instead of liquids.
Instead of throwing out the deodorising disinfecting or purifying substance or
substances in a liquid or fluid form those substances may be exposed in a solid form on
the outside of the vessel or steamer, being immersed or held in position in a cage or
otherwise attached to the outside of the vessel, so that the deodorising or disinfecting
substances may come into contact with the polluted water to be purified either at or
below the surface.
The vessel or steamer being made to sail or move about in the river or estuary the
deodorising or disinfecting substances come into contact with the greater part of the
surface of the polluted water and so prevent, stop or cure the bad odours arising from
the surface of the polluted water and especially for a time.
The deodorising or purifying liquids or fluids might be ejected by means of steam
water or gas pumps or by compressed air or otherwise as most suitable.
This system is principally intended for use in dry and hot weather.
The spraying apparatus and the suspended deodorising and disinfecting substances
may he used separately or in conjunction.

Improvements in Deodorising or Disinfecting Rivers and Estuaries
or other Sewage or otherwise Polluted Collections of Water.
I, WILLIAM PATON BUCHAN, of 21 Renfrew Street, Glasgow, in the County of
Lanark, Sanitary and Ventilating Engineer, 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 :-
This Invention has for its object to provide means for temporarily deodorising or
disinfecting rivers and estuaries or other sewage or otherwise polluted collections of
water. For this purpose a vessel such as a boat or steamer is made to move or sail
up and down or otherwise among the polluted water and when doing so there is
discharged from the sides or deck or other part or parts of the vessel or steamer or
from pipes attached thereto or therein (or beside the paddles or the screw) a
deodorising or disinfecting liquid either upon or below the surface of the water in the
shape of spray or jets as for example is done by the water spray or jets from the tube

page_text: of a water cart for watering roads or streets; or disinfecting or deodorising gas or
gases may be ejected below the surface of the water instead of liquids.
Instead of throwing out the deodorising disinfecting or purifying substance or
substances in a liquid or fluid form those substances may be exposed in a solid form
on the outside of the vessel or steamer, being immersed or held in position in a cage
or otherwise attached to the outside of the vessel, so that the deodorising or disinfecting
substances may come into contact with the polluted water to be purified either at or
below the surface.
The vessel or steamer being made to sail or move about in the river or estuary the
deodorising or disinfecting substances come into contact with the greater part of the
surface of the polluted water or of the water near the surface and so prevent stop or
cure the bad odours arising from the surface of the polluted water and especially for
à time.
The deodorising or purifying liquids or fluids might be ejected by means of steam
water or gas pumps or by compressed air or otherwise as most suitable.
This system is principally intended for use in dry and hot weather.
The spraying apparatus and the suspended deodorising and disinfecting substances
may be used separately or in conjunction.
Having now particularly described and ascertained the nature of the said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
The method hereinbefore described of deodorising or disinfecting rivers and
estuaries or other polluted waters by injecting or immersing therein or spraying
thereon deodorising or disinfecting substances, solid fluid or gaseous, from the sides
of a moving vessel substantially as described.
