PROVISIONAL SPECIFICATION.
Improvements in or connected with Apparatus for Filtering
Sewage and other Liquids.
I, THEODORE BROOKE JONES of Deneholme, Harrogate, in the County of
York, Chartered Accountant, do hereby declare the nature of this invention to be
as follows:-
The object of my invention is to so construct apparatus for filtering sewage and
other liquids, that the filtration is speedily and efficiently performed, with perfect
aëration throughout the filter whilst at the same time the said apparatus may be
cleaned with very little interruption to the filtering process.
According to my invention 1 construct a vertical open framework carrying
a series of trays placed one above the other with an air space between each; the
frames and trays are so constructed that the latter can slide and be readily
removed and changed. The said trays have perforated bottoms proportionally
smaller than the top which are filled to the required depth with suitable filtering
material, and a perforated sheet rests upon the filtering material in each tray in
order to prevent the surface cracking and at the same time to assist in distributing
the fluid more evenly over every part.
The liquid to be filtered is fed into the upper tray and descends through the
filtering material falling from one tray to the other in a finely divided state
similar to rain.
When it is necessary to cleanse any part of the apparatus one tray may be with-
drawn at a time and be replaced by another thus enabling the apparatus to be cleaned
without stopping the filtering process. It will also be readily seen that owing to
the tray formation of the filtering apparatus above described, any obstruction will
be readily detected and can at once be removed. The open construction of the
trays will keep them perfectly ventilated and entirely free from the accumulation
of noxious gases.
The filtering material contained in the trays may be of various degrees of
fineness, and I preferably arrange that the fine is contained in the upper and lower
trays whilst the centre trays contain the coarser material.
The above arrangement of apparatus may be constructed on a small scale
suitable for domestic purposes.
Dated this 30th day of December 1895.
