PROVISIONAL SPECIFICATION.
Improvements Connected with Apparatus Employed for Softening
or for Clarifying Water.
1, ARTHUR KAYE BROWN, of 1 Westminster Chambers, Victoria Street, S.W.
Middlesex, Sanitary Engineer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is certain improvements connected with apparatus
employed for softening or for clarifying water.
The first part of the invention, relates to the disposition, or method of placing
corrugated kinked or other irregular form of plates, through which the water having
the softening agent combined has to be deprived of the solid and flocculent matter
held by or suspended in it.
According to the arrangement of the corrugated, kinked, or other plates, the water
is free to pass in an upward direction, in a horizontal direction, or anglewise, either
from the bottom of a tank or from the sides or end of a tank in which the plates
are arranged.
The corrugated or kinked plates are fitted in the tank in alternate order i.e. one
plate stands on its end so that its corrugations or kinks appear vertically, the next
The water in
plate is set so that its corrugations or kinks appear horizontally.
passing through between these plates moves in a zigzag or other uneven order
according to the position at which the inflow and outflow pipes are situated.
The corrugated or kinked plates thus arranged may be all within one tank or
within two tanks for the perfect precipitation and removal of flocculent bodies by
adhesive attraction or a single tank may be partitioned or formed with two com-
partments, in both of which corrugated or kinked plates may be arranged, or in
which, one set of corrugated or kinked plates may be placed and the other com-
partment be fitted with plain plates. The corrugated, kinked, or other plates may
be perforated, or slotted, or they may have bulges to form impediments to the
direct flow of water to be clarified.
The plates are easily removable for cleansing purposes but such plates, instead of
being removed, may be suspended in the tank by chains or rods, so that they can be
lifted from the tank in bulk or in sections.
According to the second part of my invention, I use ordinary flat plates and I
support one end in a notched, serrated, corrugated, or other irregular wall of a tank,
in which said plates are free to slide when the other ends which are connected to
rods or chains are lifted by levers or appliances arranged outside the tank, so that
said plates may be agitated from the outside and be thus cleaned of the deposit
adhering to, or lodging on them, the violence of the agitation being sufficient to break
off the incrustation, which a supply of water would wash away.
The tanks are provided with the usual means of supply and discharge, also with
sludge receivers or receptacles with means for blowing the sludge out wher
necessary.

impurities contained in the water which has been treated with lime, or other agent
before it enters the tank.
Figure 3 represents a tank of a similar construction but with two cone shaped
sludge receptacles F.
Instead of all the plates being alike corrugated or kinked, as before referred to, I
place ordinary plain plates in the compartment B and kinked or corrugated plates in
the compartment but this order may be reversed and instead of the water entering
at the bottom by the pipe D, so as to flow from the bottom to the top of the tank it
may enter at any other part, such as midway up, so that the more solid or heavier
particles held by the water may at once fall to the bottom of the tank the lighter
particles only rising with the water to flow down the channel A into the compart-
ment C.
"
The plates, of whatever kind is used, can be lifted singly out of the compartment,
or bodily en bloc" if placed on a frame capable of being dropped into the tanks
which will facilitate their easy removal for scraping purposes.
Instead of the plates being removed for cleansing purposes I show at Figure 4 a
system of suspending_the_plates plain, corrugated, or kinked by the rod H from
notched or serrated side walls of the tank, said rod having a series of washers or
projections for supporting the plates at their inner ends, which plates when the
Hocculent deposit matter has to be removed can be lifted up and down by the
handle I, or by the hand lever J in order to give a tremulous motion to the plates
when required.
Instead of the rod H and cross pieces, the plates may have their ends attached to
a chain it being only essential that sufficient space be left for the passage of water
from one row of plates to another.
By this arrangement the water may be caused to pass in a zigzag direction between
every two or more plates as series i.e. the two or three lower plates may be set
against one side wall of the tank leaving a space between the plates and the opposite
side wall of the tank, the next series of plates in any number being arranged in the
alternate order, so that the water entering at the bottom through the pipe D would
pass up between the lower set of plates from one side of the tank and then
up between the next. layer of plates, so that the water travels upward and
horizontally in alternate order from opposite sides of the tank and from the number
of turns the water has to travel within the tank it is very much retarded in the flow
and a perfect precipitation of the solid and flocculent matter is ensured.
The plates preferably used for my invention are the ordinary corrugated or
kinked plates, such as are used for Roofs of buildings.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The employment of corrugated or kinked plates arranged in reverse_alternate
order, as indicated at Figure 2 of the annexed drawings, in tanks, as at Figure 1,
for causing an adhesive attraction of the solids and flocculent bodies held by water
during its flow through between said plates for the purpose described.
2. The modified arrangement of plates shown in Figure 3 of the annexed drawings
for the purpose described.
3. The means by which suspended plates can be supported and be agitated for
cleansing purposes without removal from the tank, when said plates are employed for
the purpose herein before described.
