What role does the concentration of dissolved gas play in filtration?

The concentration of dissolved gas significantly influences the filtration rate and loss-of-head in water treatment processes. When gases such as oxygen or carbon dioxide are dissolved in water, they can change the physical and chemical characteristics of the water, which subsequently impacts filtration efficiency.

Increased levels of certain dissolved gases can lead to the formation of bubbles during filtration, which can obstruct filter media and increase resistance, resulting in a higher loss-of-head. The presence of these gases can also alter the viscosity of the water, affecting how easily it can pass through filter materials. Ultimately, a well-established understanding of how dissolved gas concentrations impact these aspects is crucial for optimizing filtration performance and ensuring effective treatment outcomes.
