IDS has a unique product that breaks through Biofilms comprised of Glycocalyx which are created from extracellular polymeric substances excreted by bacteria. These sticky polymers hold the biofilm together and cement it to the duct wall. The biofilm traps nutrients and protects the underlying bacteria from biocides including bleach. These inert coatings allow for the accumulation of complex, metabolically cooperative bacterial communities that often produce highly pungent odors. Biofilms often permeate through all levels duct systems. Testing conducted by Sandia National Laboratories indicates that the formulation is "extremely effective" for the complete decontamination of biofilms on all test surfaces.
