How Magnesium Helps Clean Water and Fights the Cold

Magnesium (Mg) is revolutionizing wastewater treatment. It's not just about removing nitrogen and recovering phosphorus; Mg enhances the entire process, especially in cold temperatures.

Cold Weather Efficiency

In cold weather, around 13.4°C, adding Mg boosts nitrogen removal by 23% compared to not using Mg. This is a significant advancement for regions with cold climates. Mg helps bacteria work better by improving their energy use and electron transfer.

Bacterial Cohesion

Mg also helps bacteria stick together. It increases the production of sticky proteins and makes them more hydrophobic. This aids in forming granules, which are easier to handle in treatment plants.

Bacterial Synergy

The bacteria in these systems work together efficiently. About 73% of their interactions are positive. The main players are anammox bacteria and denitrifiers. Other bacteria contribute indirectly, making the entire system more efficient.

Reliability in Cold Weather

This process is reliable even in cold weather. It demonstrates that Mg is key to making wastewater treatment effective year-round. This is crucial for ensuring clean water, regardless of the weather.
