Need to increase of pH
Apr 26^th, 2012, 2:40am

In a closed biofilter system (2000 L), there is desired a pH change.
Now in my biotrickling filter system reduce the pH to 5.18 from 7. Now I want to maintain the pH range 6.5 to 7. What volume of CaCO3 must be added in order to attain the desired pH of 7.
I want to know the correct volume of CaCO3 to be added and the calculations for such a problem. Thanks in advance.

Depending on what is in the sample, a calculation can be 100% off or more.
