The pH control system uses an LMI 5000 pH controller and probes integrated with carbon dioxide in 50 lb. or 600 lb. returnable containers or bulk to decrease the pH of water. The process of adding carbon dioxide to water converts the carbon dioxide to carbonic acid in the water, thereby decreasing the pH. The system includes the pH controller, pH probe, gas regulator, cryogenic solenoid valve, diffuser and delivery/replacement of the CO2 tanks as needed.
