GAS APPLICATIONS

A safe and economical neutralization of alkaline wastewater is carried out with carbon dioxide (CO₂). The environmentally friendly carbon dioxide prevents acidification and increased salt content of the water.

Advantages of CO₂ over mineral acids

• Safe and easy pH control; Acidification is not possible
• No handling of dangerous, aggressive acids
• no increase in salinity;
• Prevents corrosion when reusing treated wastewater
• no investment costs
• low operating costs
