pH Control

Using carbon dioxide to control the pH of water is a safe way to minimize environmental exposure and the risk of catastrophic accidental injuries. This low-cost treatment option substantially reduces costs of the ongoing process, infrastructure, maintenance and compliance. In addition, our carbon dioxide pH control solution reduces the high cost required to deliver, store and use hazardous mineral acids – including the ongoing degradation costs of equipment exposed to the corrosive effects of acid.
