What Role Does CO2 Wastewater Treatment Play in Industry ...

CO2 Wastewater Treatment Offers an Effective, Safer and Environmentally Friendly Solution. An alternative treatment solution is CO2. When injected directly into wastewater, CO2 causes the formation of carbonic acid, which naturally adjusts the pH to a suitable level. This treatment method is easy to control, and the byproducts it creates are harmless.
