Over the past decade, rapid changes in the water treatment industry have been seen in all industrial segments. These changes (water recycle & water reuse) increase the potential for biofouling. Biofilm formation can create corrosion problems in industrial water systems. Control of biofilm is achieved most effectively when the mechanism of formation is understood. It may be possible to reduce the biomass by adding an appropriate biodispersant to the system. However, biodispersant activity in water systems is poorly understood, partly because of a lack of screening methods for rapid evaluation on these types of chemicals.

The key to measuring the effectiveness of any biodispersant, is the ability to quickly and accurately measure its efficacy using technology such as the ATP assay and correlating the results to biofilm removal.
