dissolved oxygen
Dissolved oxygen is a factor affecting the performance of nitrifying bacteria.
Heterotrophs have greater numbers than nitrifiers in wastewater and are more efficient at scavenging oxygen. In mixed populations with low D.O., the heterotrophs will be able to quickly use the available oxygen faster than the nitrifers since oxygen is also consumed in heterotrophic metabolism. It is a good idea to increase the D.O. levels with high incoming BOD or NH3.
Remember: D.O. levels increase with colder temperatures and decrease in warmer temperatures.
