Cost of First Plant, etc.

Installation of Second Plant. Cost Advantages. Output
and Strength of Fluid.
On account of the demand for the fluid, the dismantling, overhauling
and cleansing of the apparatus had to be carried out on Sunday, the men
working overtime; this, together with the fact that to meet the public
demand overtime had to be resorted to and the supply to the Works
Department curtailed, induced the Committee to consider the advisability
of recommending the Council to purchase an additional plant. There was
no need for new saturators.
In view of the difficulty of meeting the demand for the fluid, and of
the use of the disinfectant in connection with the Public Swimming Baths,
the Public Health and Housing Committee were of opinion the duplication
of the plant was necessary, and recommended the Council that additional
plant, as specified, for manufacture of disinfecting fluid by Electrolysis, be
obtained and fitted up at an estimated cost of £430.
The new plant has been installed whilst this report is being written
(February, 1910) and is as follows:—
Four Electrolysers* good for an output of 25 gallons of fluid at a
* The tanks were, made of earthenware (which if well glazed will never wear out).
Earthenware is one of the best insulating materials. Tanks made of slate contain iron
(it seems impossible to obtain slate free from iron) and were being constantly destroyed
by the action of the electric current and had to be often replaced.
