pH Adjustment with co2 Injection Improves Wastewater Treatment
Why controlling pH with co2 injection can greatly improve efficiency, reduce cost, and avoid the use of dangerous chemicals in all industrial wastewater treatment processes.
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.
