At NINGBO INNO PHARMCHEM CO.,LTD., we are dedicated to understanding the intricate chemical processes that drive effective environmental solutions. Sodium Formate, a simple yet powerful organic salt, plays a key role in biological nutrient removal (BNR) from wastewater. This article explores the underlying chemistry that makes Sodium Formate so effective in these critical applications.

In biological wastewater treatment, microorganisms are the workhorses that break down pollutants. For processes like the partial denitrification-anammox (PD–A) pathway, which is vital for nitrogen removal, the availability of suitable carbon sources is essential. While traditional carbon sources like acetate are common, they can sometimes lead to the overgrowth of unwanted heterotrophic bacteria, compromising system stability. Sodium Formate emerges as an advantageous alternative, often supporting the growth and activity of the specific bacteria involved in nitrogen removal more effectively.

The chemical structure of Sodium Formate (CHNaO2) allows it to be readily utilized by certain microorganisms as a carbon and energy source. In the context of sodium formate biological nutrient removal, it can serve as a preferred substrate for bacteria that facilitate the reduction of nitrates to nitrites, a key step in the denitrification process. Research has shown that formate can be assimilated by key bacteria like *Candidatus Brocadia*, primarily through metabolic pathways such as the Wood–Ljungdahl pathway. Furthermore, other bacteria, like *Desulfobacillus*, can utilize formate and, in doing so, produce essential nutrients or metabolites that support the growth of anammox bacteria.

This symbiotic relationship, facilitated by the presence of Sodium Formate, enhances the overall efficiency and stability of the PD–A process. It leads to a more abundant and active community of anammox bacteria, contributing to higher nitrogen removal efficiencies. The improved performance and stability observed in studies involving sodium formate in wastewater treatment highlight its chemical advantage as a targeted nutrient for specific microbial communities.
