In biological filters, what benefit is produced by non-pathogenic microbes?

In biological filters, non-pathogenic microbes play a crucial role in the treatment process by effectively breaking down organic matter and converting harmful substances into less toxic forms. One significant benefit of utilizing these non-pathogenic microbes is their contribution to low chlorine demand in the disinfection process.

When non-pathogenic microbes are active in the biological filter, they help assimilate organic compounds, thereby reducing the overall organic load in the water. This lower organic load means that there are fewer substances that chlorine would need to react with during disinfection. As a result, the amount of chlorine required to achieve effective disinfection is reduced, which leads to a lower chlorine demand.

Additionally, this contributes to better water quality and minimizes the formation of disinfection byproducts, which can occur when chlorine reacts with organic materials in the water. In essence, non-pathogenic microbes enhance the efficiency of water treatment processes while maintaining the safety and palatability of the final water product.
