Carbon Dioxide for pH Control

Harnessing Carbon Dioxide for Precise pH Regulation. Lime softening processes for drinking water include a step for pH adjustment, after settling. Gaseous Carbon Dioxide (CO2) is a simple and affordable alternative to acid, but it is often used inefficiently – wasting CO2 gas, requiring too much energy, or the need to use finished water for the carrier stream. The Speece Cone, by ECO2, provides a highly efficient solution for rapidly dissolving CO2 into a process water stream for effective pH control.
