pH Control of Process Water and Wastewater

Eliminate the risks of mineral acid-based systems used for pH control of process water

Delivering process solutions that lower operating costs while creating safer site conditions and improving your environmental footprint is important to you and your team. If your current pH adjustment system is using minerals or a strong acid like sulfuric acid, you can now consider an alternative, more eco-friendly process water treatment using carbon dioxide.

What are your challenges?

Difficulty controlling water or wastewater pH resulting in large swings

Airgas can help you improve your process control and stabilize pH with our carbon dioxide solution

Handling sulfuric and hydrochloric acids isn’t safe for my team

Carbon dioxide is much safer for your team and the community where you operate

Using sulfuric and hydrochloric acids is expensive

Carbon dioxide is a cost-efficient alternative that does not require significant capital investment

Eliminating dissolved solids or additional sulfates & chloride in discharge

CO2 does not add dissolved solids or destroy alkalinity, providing a safe, environmentally friendly alternative to strong acids
