can anyone name a process that can remove carbon dioxide from water. and two processes that can?

Question

return it

Answer 1

You can remove CO2 by boiling

It will return if you just leave it for enough time (atmospheric CO2 will dissolve) or you can heat a carbonate salt e.g. CaCO3 and pass the produced CO2 gas through water or burn a hydrocarbon with lots of oxygen and again pass the formed gases (CO2 and vapor) through water.
