Treating Your Water with a Biological Filtration System
The biological treatment of water pollution actually involves taking naturally occurring bacteria and implementing the species in an advanced water filtration process. Rather than cleaning water with chemicals, the biological method pairs reverse osmosis with bacteria that can remove contaminants from drinking water.

Microbial Survey of a Full-Scale, Biologically Active
Biologically active filtration is commonly used in Europe and Asia for drinking water treatment . Biological processes have the potential to cut operation costs by decreasing the amount of chemicals required for treatment and increasing effectiveness in terms of decreased biological regrowth (e.g., corrosion, nitrification, taste, and odor) in the distribution system (DS) and decreased chlorine demand (6, 17, 30).

Drinking Water Treatability
Biological filters remove contaminants by three main mechanisms: biodegradation, adsorption of micropollutants, and filtration of suspended solids. The microbial growth attached to the filter media (biofilm) consumes the organic matter that would otherwise flow through the treatment plant and ultimately into the distribution system.
