GAS APPLICATION

For pH adjustment before coagulation, CO₂ is the acid of choice. Dissolved in water, CO₂ reacts as a weak acid which is excellently suited for the precise adjustment of the pH value in water. The figure below shows the typical flat neutralisation curve with weakly acidic carbon dioxide compared to a strongly acidic mineral acid.

MESSER SOLUTION

For the rapid and complete dissolutionof CO₂, Messer supplies diverse, widely tested technologies, varying from fine-bubble injection directly into the main water stream to complete dissolution in a side stream under hydraulically defined conditions. In each project, we specify and offer the injection and control technology. Additionally, we calculate your CO₂ demand.
