Dear Mohsan We need more ...

Dear Mohsan

We need more informations on concentrations of some ions (Ca++, Na+, HCO-, CO3-, SO4-- and Cl-) corresponding to PH 7.1 and PH 9.8 to 10.1, and saturation Index vis a vis of Calcite and Dolomite.

The increasing of PH during the transportation can suggest loss or degasing of CO2 in the pipe. At PH 9.8 to 10.1 we have precipitation of Calcite and dolomite. So, concentration of Ca++ and Mg++ decrease in water.

Please let us have more informations on these ions.

Thanks.
