Can carbon dioxide and calcium hydroxide be used as refining agents in brine? How to do it specifically

It is possible to first add calcium hydroxide to remove the magnesium ions present; the standard is that the excess ash content in the solution after the reaction should be between 0.2 and 0.8 tt. After the solution becomes clear, carbon dioxide can then be added to remove the calcium ions.

Doesn’t this increase the calcium in the saltwater? Does it cause pressure for subsequent removal of calcium carbonate? Where are the practical applications?

There is a secondary purification step: after removing magnesium, carbon dioxide is added in the calcium removal tower to remove calcium.
