pH control

Using carbon dioxide to control the pH of a site's wastewater offers measurable safety and cost advantages over treatment systems that employ toxic and corrosive mineral acids such as sulfuric acid. Carbon dioxide is a safer alternative that minimizes environmental exposure and the risk of catastrophic accidental injuries. This low-cost treatment option substantially reduces the ongoing process, infrastructure, maintenance and compliance costs. 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.
