strength of * 4 grammes of Chlorine per litre and suited for a
240 volt circuit.
One Electric Motor (for a 240 volt circuit), arranged to hang vertically
and driving two stirring machines.
Two Stirring Machines running on ball bearings and fitted with
suitable grooved pulleys.
Two Ebonite Stirring Rods fitted to machines.
A Constant Head Flow Regulating Tank, suitably coated with
preservative paint.
A Flow Regulating Cock with vernier.
A Mixing Tank of latest pattern.
A Switchboard mounted with 2 D.P. Switch good for 25 amps in
cast-iron case.
4 S.P. Porcelain Tubular fuses;
An Ampere meter;
A Voltmeter;
with provisions for the Council's meters.
A Series Rheostat.
By including (as mentioned above) a stirring motor of vertical
pattern, two stirring machines and two stirrers—one working on the old
plant and one on the new—the production is made practically automatic
and enables both plants to be worked simultaneously, and necessitates no
addition to the staff.
The cost of the entire plant as specified was £430; the Council
provided rough labour that was required in addition.
The saturated solutions are now lifted into the large top supply tank
by means of a pump instead of being carried up by hand in pails, a matter
occupying ten minutes instead of an hour and a half.
The two plants can deliver in eight hours 400 gallons of electrolytic
* With a current of 25 amperes there is obtained over 6 grammes of chlorine per
litre. This efficiency is no doubt due to the new shape of the electrodes and to the
earthenware tanks.
