Application of Speat Oxide.
DANIEL MACLEOD NELSON, 53, Waterloo Street, Glasgow, Chemical Engineer,
and GEORGE RITCHIE NELSON, 53, Waterloo Street, Glasgow, Commercial
Manager, do hereby declare the nature of this invention to be as follows:-
The application of the material known commercially as spent oxide" to the
deodorizing and the filtering of sewage, and to the absorption of the manurial
elements of animal and other urine and refuse, and the employment of same
thereafter as a fertilizer.

Improvements in the Treatment of Sewage, Urine, and Refuse
Materials, and the Production of Fertilizers therefrom by the
Application of Spent Oxide.
DANIEL MACLEOD NELSON, 53, Waterloo Street, Glasgow, Chemical Engineer,
and GEORGE RITCHIE NELSON, 53, Waterloo Street, Glasgow, Commercial
Manager, 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:-
(e) The invention consists of the admixture of oxide of iron natural or artificial
and whether in a fresh partially spent or fully spent condition with sewage
urine drainings and refuse materials for the absorption of their manurial pro-
perties and the use of same thereafter for fertilizing purposes
The amount of oxide required in the process is ascertained by the odour it
gives off when fully charged with manurial properties.
The manner in which the invention is carried into effect is as follows-A
quantity of oxide is laid in any convenient part of the works, stables, byres,
cattle-pens, sheds, or other premises adjacent thereto, to which the sewage,
urine and excrements may flow or be conveyed and caused to filter through,
flow over, or mix with it, the result of which is the absorption by the oxide of
the useful manurial and fertilizing elements contained in these and similar
refuse and waste materials and the production-by their combination of
fertilizers. In like manner the application of the oxide to stable manures-
071

page_text: dung, drainings, and litter-by layers, spread between, and the sprinkling over
of the deposits during the period of collection in the stable and farm yards,
depots, fields or other manure repositories for the purpose of laying hold of, and
retaining until required by the soil, the nitrogen (forming sulphate of ammonia),
potash, phosphates, and the like valuable manurial elements contained therein,
forming a natural plant food and fertilizer.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that
what we claim is novel:-
(1) In respect that such oxide of iron has not been used hitherto in the
manner described.
(2) That by this invention useful manurial properties which have escaped
unprofitably are now controlled, and rendered substantially valuable and of
important public utility.
