Effect of residence time and of anti-scalant SHMP on CaCO3 precipitation in a CSTR
- •
As expected increase of the anti-scalant SHMP dosage reduced CaCO3 precipitation.
- •
However unexpectedly increase of the residence time decreased CaCO3 precipitation.
- •
This decrease is shown to arise from increased SHMP adsorption on CaCO3 particles.
