Biological Activity Reaction Test (BART) biodetectors are excellent microbiological diagnostic tools used to identify the presence of process disruptors. Find out if you have bacteria creating slime layers and limiting disinfection, or if iron-reducing bacteria are corroding your pipes. Tests for many types of bacteria are available, including sulfate-reducing bacteria, heterotropic acid, nitrifying bacteria, pool and spa bacteria, blue-green algae, and more.
