Wastewater Treatment co2 pH Adjustment Equipment
Proportional CO2 pH Control System with Internal Pressure Regulator
The pH control system uses a programmable pH controller and pH probe integrated with a pressure regulator to utilize carbon dioxide to decrease the pH from basic to neutral (7.0 +/-).

Control Box
The process of adding carbon dioxide to water using gas diffuser(s) converts the carbon dioxide to carbonic acid in the water, consuming alkalinity, thereby decreasing the pH.
The system includes the pH controller, pH probe, gas regulator, NEMA double control panel with view cover and stainless steel stand.
The system is easy to calibrate and uses 120-volts AC, 3 amps, for power.
The benefits as compared to mineral acids are as follows:
- Pressure regulator internal to control box, protected from elements
- Non hazardous (documented inventory or manifests)
- No drum disposal costs
- No secondary containment needed
- Minimal EC/TDS addition, making the water reusable in many applications
such as higher cycles of concentration in cooling towers prior to discharge - CO2 operating costs are less than using mineral acids
- CO2 is available in 50 lb, 600 lb and bulk containers
