Traditionally referred to as the biochemical oxygen demand (BOD) test, this test evaluates the potential demand for oxygen that would be created by the degradable organics in an effluent.

The BOD test has become a standard regulated procedure that is applied to determine the potential oxygen demand that would be created by discharging liquid effluents into natural water systems.

Of the various BOD test procedures, it is the 5-day BOD test that has become recognized as the standard test to generate a BOD5 estimation of the total biochemical oxygen demand.

The major differences between the generation of a BOD5 and a patented BODBART is that the former employs dilution to achieve the “correct” value for the oxygen demand (through a partial depletion from oxygen saturated state in the test) while the latter does not dilute the test sample but evaluates the demand for oxygen by the time that it takes the indigenous organisms to

create a reductive condition primarily as a result of the respiration (and removal of) of the saturated oxygen present in the sample at the beginning of the test.

It is therefore claimed that the BODBART is generated in a more scientifically defensible manner than the BOD5 for the evaluation of the intrinsic oxygen demand inherent in the sample and activated sludge treated municipal wastewaters.

This would be generated as a BODBART number generated in seconds that would have a similar precision to, and be faster and more convenient than the BOD5 test.

The main objective in the patented BOD-BART system therefore is to provide an easy and rapid alternative testing system for the determination of BOD5 in municipal aerated lagoon.

Beside our BOD tester we offer also N (nitrifying) and DN (denitrifying) testers.
