ABSTRACT:
A method is disclosed for measuring viability of a waste treatment basin biomass contained in a waste basin mixed liquor comprising measuring the rate of oxygen uptake in a first sample of said waste basin liquor; measuring the rate of oxygen uptake in a mixture of a second sample of said waste basin liquor and a sample of synthetic petrochemical reference liquid; subtracting to determine the differential of said rates; and effecting, by predetermined correlation with differential oxygen uptake rate, a determination of the viability of said biomass based on said differential oxygen uptake rate for said waste basin liquor.
