Biodispersant and Biocide Performance Booster

Did you know that more than 99% of the microbial growth in a given system is often found adhering to various surfaces in the form of biofilms? These micro-organisms are not accounted for in typical tests performed on the system water but are responsible for reduced heat transfer efficiency, corrosion, flow restrictions, increased operating and maintenance costs, and increased risk to health and safety. 

AQUAGUARD 620 is a biodispersant, specifically designed to enhance the efficacy of your biocide treatment program to help penetrate, remove and disperse biofilm.

AQUAGUARD 620 functions through three main mechanisms; detergency or cleaning, wetting and defoaming. Detergency reduces the ability of biofilm to adhere to system surfaces thus allowing them to be more easily removed with the water flow through the system. Wetting helps to increase the ability of the biocide treatment to penetrate the biofilm and attack those organisms beyond the surface. Defoaming helps reduce the copious quantities of protein-soil based foams often associated with the breakdown and removal of biofilm during the cleaning process.

AQUAGUARD 620 is nonionic in nature and compatible with all biocide treatment programs.


  • Combines detergency, wetting and defoaming capabilities
  • Reduces the adherence of biofilms to system surfaces allowing them to be more easily removed
  • Enhances the ability of biocide treatment to penetrate biofilms, killing the micro-organisms below the surface
  • Reduces the degree of foaming from the biofilm removal process
  • Provides cleaner system surfaces thus making for more efficient heat transfer and reducing under deposit corrosion
  • Biofilm removal helps to reduce microbial based health and safety concerns
  • Use improves system efficiency, reduces operation and maintenance costs and improves heat transfer


AQUAGUARD 620 is ideal for use in cooling water systems such as cooling towers and re-circulated and once through cooling water systems.
