How do you remove the CO2 from the water?

To remove CO2 from water, you can use methods such as aeration, where air is introduced to the water, allowing CO2 to escape into the atmosphere. Another method is to heat the water, as increasing temperature decreases the solubility of CO2, facilitating its release. Additionally, chemical methods, such as adding alkaline substances like sodium hydroxide, can react with CO2, forming carbonate compounds and effectively reducing its concentration in the water.
