The environment contains a myriad of different bacteria that are all capable of causing problems.

These problems can range from slimes, plugging, discoloration and cloudiness to corrosion and infections.

The biological activity reaction test (BARTTM) is a water testing system for nuisance bacteria and can involve several different tests. These tests detect the activity (aggressivity) of these nuisance bacteria by the time lag (TL, measured in the number of days from the start of the test to when a reaction is observed). The longer the TL before the observation of activity, the less aggressive the bacteria are in that particular sample. There are seven different tests that are recognizable by colored cap coding and the initial letters preceding the word BART.  These include selective tests for:

Iron Related Bacteria                   IRB-BARTTM                   Red Cap

Sulfate Reducing Bacteria            SRB-BARTTM                  Black Cap

Heterotrophic Aerobic Bacteria    HAB-BARTTM                Blue Cap

Slime Forming Bacteria                SLYM-BARTTM           Green Cap

Denitrifying Bacteria                    DN-BARTTM                    Grey Cap

Nitrifying Bacteria                       N-BARTTM                          White Cap

Fluorescing Pseudomonads           FLOR-BARTTM            Yellow Cap

Acid Producing Bacteria              APB-BART™        Purple Cap

Biochemical Oxygen Demand      BOD-BART™        Light Blue Cap

Major advantages

1.You do not need a laboratory to set up the test to determine whether there are aggressive bacterial problems in the sample being tested. They are easy to read since the signals (reactions) generated are observable.

2. The BART™ testers provided a greater variety of environments within which the bacteria of concern can grow. This is a very major advantage over the traditional agar techniques in common use in the microbiology laboratories today. This feature makes the BART™ testers far more sensitive and reactive to aggressive bacterial populations.

These are two main advantages in using the BART™ testers since they offer convenience, simplicity, sensitivity and durability.

Convenience means that the techniques employed to set up the test is easy to follow. The BART™ testers are supplied in individual, moisture proof, foil pouches that prevent the tester from degenerating as a result of premature rehydration.

Shelf life is 4 years.
