Hi All,

I am trying to calculate the effect of reducing NaOH dosing rate on the pH.
Its difficult to explain so I've attached the excel file.

Regards,

Any tips are well appreciated!



 
Sorry should add that the reason why I am reducing the NaOH is that I am adding milk of lime solution in the preceding stages.

I am aware that the pH will increase significantly which is why I need to reduce the NaOH in the preliminary steps and set up a new pH set point.

I am trying to calulate how much the pH changes for the addition of milk of lime solution (reducing NaOH dosing rates)
