How does the reaction between CO2 gase and alkaline wastewater to reduces TDS Concentration in foundry industries?

Best insight from top research papers

The reaction between CO2 gas and alkaline wastewater in foundry industries reduces Total Dissolved Solids (TDS) concentration by neutralizing the alkaline wastewater . This process involves injecting carbon dioxide gas into the alkaline wastewater to adjust its pH, which leads to the formation of stable carbonate minerals that sequester CO2. By utilizing the Fenton process, which involves the generation of hydroxyl radicals through a mixture of hydrogen peroxide and iron salts, pollutants in the wastewater can be degraded effectively, leading to a reduction in TDS concentration. The combination of these methods allows for the efficient treatment of alkaline wastewater in foundry industries, resulting in a significant decrease in TDS concentration through neutralization and pollutant degradation.

What is the role of degasser columns in industrial water treatment systems?5 answersDegasser columns play a crucial role in industrial water treatment systems by removing gas molecules entrapped or dissolved in the processing liquid. These columns consist of a vacuum chamber with inlets and outlets for the liquid to pass through, separators that allow gas molecules to permeate through but not the liquid, and a vacuum for applying pressure differential across the separators. The degasser columns effectively remove entrapped or dissolved gas from the liquid, improving the quality of the water. In the context of distillation columns, suitable control of these columns is necessary for troubleshooting purposes and to ensure satisfactory operations. In the case of sterilization systems, degasser columns are used to remove ozone particles from the air within the mixing chamber, preventing their expulsion and ensuring the safety of the process.

How does CO2 affect water pH?5 answersElevated atmospheric CO2 levels can affect water pH. Studies have shown that increased CO2 concentrations can lead to a decrease in pH, making the water more acidic. This decrease in pH is due to the formation of carbonic acid when CO2 dissolves in water, which releases hydrogen ions and lowers the pH. The solubility of CO2 in water can also lead to changes in pH, especially at high pressures and temperatures. Additionally, the presence of CO2 can affect the pH compensation abilities of fish, with reductions in extracellular pH compensation observed. It is important to note that the effects of CO2 on water pH can vary depending on factors such as salinity and the type of water body (eutrophic or oligotrophic).
