pH Adjust co2 Control Unit

These pH control systems use a programmable pH controller and pH probe to proportionally control the flow of carbon dioxide direct injection into any flowing liquid. This decreases the pH from a basic level to a programmable set point on an ongoing automated basis.

This carbon dioxide injection in water using gas diffuser(s) converts the carbon dioxide to carbonic acid in the water, consuming alkalinity, thereby decreasing the pH.

The system is easy to calibrate and uses 120-volts AC, 3 amps, for power. The system includes the sc100 pH controller, pH probe, gas regulator, NEMA 4X control panel with swing out sub panel, clear window and optional stainless steel stand.

CO2 is commonly available in 50 lb, 600 lb and bulk containers. All components are neatly housed in the compact enclosure that can either be wall mounted or free standing with the optional stainless steel stand. The system supports gas flows up to 500 CFM.

Benefits of CO2 VS. Mineral Acids

  • Non hazardous (documented inventory or manifests)
  • No drum disposal costs
  • No secondary containment needed
  • Minimal EC/TDS addition
  • CO2 operating costs are less than using mineral acids
  • No liability for operators

Automated pH Adjustment with co2 Injection

Why control pH with co2?

In wastewater treatment, a pH control system that uses a programmable pH controller and pH probe to proportionally control the flow of carbon dioxide injection decreasing the pH from a basic level to a programmable set point, can substantially streamline any pH adjustment process.

The process of adding carbon dioxide to water using a gas diffuser(s) converts the carbon dioxide to carbonic acid in the water, consuming alkalinity, thereby decreasing the pH. This type of system is very easy to calibrate and can use as little as 120-volts AC, 3 amps, for power. When automated, these systems will also include a pH controller, pH probe, gas regulator, a control panel and can be mounted in a number of ways. CO2 is commonly available in 50 lb, 600 lb and bulk containers.

In a well designed automatic pH control system, all components are neatly housed in a compact enclosure that can either be wall mounted or free standing on a stand. These systems can be scaled to support virtually any gas flow with most not exceeding 500 CFM.

Using direct injected co2 for pH adjustment in your wastewater treatment process can provide you with many benefits. This can save you money and effort.

Benefits of CO2 VS. Mineral Acids:

  • 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
  • No liability for operators
  • CO2 is available in 50 lb, 600 lb and bulk containers
