Operational Considerations
- 1 kg COD requires 1.2 kg of oxygen
- 1 kg COD makes about 0.15 kg secondary sludge, more if the D.O. is under 1.5 ppm
- In the U.S. offsite generated LOX usage costs the same as using electricity at $0.07/kW-hr.
- In the U.S. onsite generated oxygen usage costs the same as using electricity at $0.05/kW-hr.
