Adding a concentrated solution to a tank with its own concentration

[springer_duke]

Hi, I am needing to add X volume of a high concentration solution to a tank with a low concentration solution already in it. All of the calculations I am finding online are for dilutions, but technically I will be concentrating a solution. I just want to know how much of the extremely high solution I should add to the tank to keep the new solution concentration below the required regulatory concentration. Thanks for any help

If you know the actual concentration of the highly concentrated solution and the tank volume, then you can do a mass balance of the target compound between the tank and the incoming stream.

The principles of dilution still apply; conservation of mass

(m.sol1 + m.sol2)/(m.sol1 + m.sol2 + m.wat1 + m.wat2)
TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!

Yes, but you'll also be diluting the concentrated solution.

Good Luck,

You should do chemical engineering if you are not a chemical engineer….
