Description
Given:
the water flow to be treated
the fluoride concentration desired in the trated water
the fluoride concentration in the solution to be prepared (dillution rate)
calculates:
the fluossilisic acid mass to be stored
the fluossilisic acid volume to be stored
the volume of solution to be prepared
the flow of the solution to be dosed.
It is assumed that:
the fluossilicic acid solution density is 1.25 kg/L
the fluossilicic acid concentration in the solution is 25 %
the fluoride ion concentration in the acid is 79.02 %
