Hi there!

Just another quick question regarding bio treatment of wastewater:

What sort of residence times do you think would be needed for a specified throughput? Do you have any figures or sources for this kind of data?

Cheers,

Lisa.

The residence time required would depend on a number of factors like:

1. The BOD/COD loading to the biotreatment
unit which in your case is directly related
to the quantity of oil needing treatment.

2. The actual "treatability" of the waste
in the water. One measure of this is the Monod rate constants for the particular waste.

3. The presence or absence of biological inhibitors and/or nutrients.

4. The desired endpoint concentration of oil in the waste.

5. The total volumetric flow to the treatment unit.

If your waste is unusual, then a lab treatability study would probably be recommended to determine the design parameters for the full scale unit.
