Electrolytic Disinfecting Fluid.
The electrolytic disinfecting fluid as manufactured contains approximately
9-10 grammes per litre of free chlorine and is broken down to a
strength of approximately 4 grammes per litre for distribution.
During the year 1932, 61,940 gallons were manufactured and broken
down to 127,500 gallons of weaker solution for distribution.
The production of the solution at a strength of 4 grammes of available chlorine per litre has averaged 111,373 gallons per annum for three years at an average annual cost of £2,274, the cost per gallon thus being 5d.
