Abstract
A simple, and effective tool to measure BOD with a 98% correlation to theoretical BOD values has been developed using a technique of continu ous short term measurements of O-2 consumption rates. Measurement time s are in the range of 5 to 10 h depending on the initial BOD, instead of 5 days required in the conventional BOD5 analysis. A bioreactor con taining calcium alginate entrapped activated sludge microorganisms was used with phenol and hydroxybutyric acid (HBA) as model substrates.
