1. Shaded pHrox results are those pHr- 2.0 Units‘or pH <3 at

 

2. Shaded TAA, Spos & % So, results are those exceeding the QASSIT action levels of 18 mol H'it or 0.03 %S.
3, Acid-Base Account = Total Acidity (ie. Potential + Actual + Retained) - Total ANC, but not less than TSA.

4, Required Lime Rate is calculated from the net Acid-Base Account with a factor of Safety = 1.5
