Precipitation risks of carbonate species due to stripping of dissolved CO2 in aquifer water

Greetings to all!

I wanted to know the risks of scaling in ground water/aquifer pretreatment process when we have a deaerator or air stripper column in the treatment scheme.  For cases wherein ground water/produced water needs to stripped of dissolve hydrocarbon gases, we need to employ an air stripper column followed by liquid phase GAC media.

My concern is what would be the effect on CaCO3/MgCO3 species due to the addition of the stripper column.  The end water quality only requires reduction in dissolved hydrocarbon gases, as the water will be injected in the well and some of it will be in used for floor washing, gardening.

Please enlighten me on trouble shooting aspects for scaling issues in the air stripper column.

Best Regards
