Biological Nutrient Removal (BNR)
Improving Nitrification with Bioaugmentation
Bioaugmentation with nitrifying bacteria can help support nitrification efficiency in wastewater treatment systems, particularly when existing microbial populations are insufficient or recovering from process disruptions.
Nitrification depends on specialized microorganisms that biologically oxidize ammonia to nitrite and then nitrate. These organisms grow more slowly than many of the heterotrophic bacteria responsible for removing carbonaceous organic matter.
Introducing microorganisms that metabolize carbonaceous biochemical oxygen demand (cBOD) can also support nitrification by reducing competition for dissolved oxygen and other treatment resources.
Supporting Ammonia Removal with Specialized Microbiology
A balanced bioaugmentation program may include concentrated populations of both:
-
Nitrifying microorganisms that support ammonia oxidation
-
cBOD-degrading microorganisms that reduce biodegradable organic loading
Reducing cBOD can create more favorable conditions for nitrifying populations and provide additional treatment capacity for ammonia removal and nitrogen conversion.
BioLynceus® provides live microbial cultures designed to supplement biological wastewater treatment systems with microorganisms that support nitrification, cBOD reduction, and overall treatment stability.
Denitrification with Candy Carbon®
Download White Paper Here Even with BNR, denitrification can be challenging when the plants are underloaded for flow as well as biological or biochemical oxygen demand (BOD) and perhaps chemical oxygen demand (COD). Denitrification is inhibited by a lack of available...
