Biofouling in recirculating water systems may be controlled by admixing or otherwise providing 1-bromo-3-chloro-5, 5-dimethylhydantoin (“BCDMH”) to the water at a level effective to control biological film-forming organisms and thereafter maintaining the BCDMH concentration at a level sufficient sub

Biofouling in recirculating water systems may be controlled by admixing or otherwise providing 1-bromo-3-chloro-5, 5-dimethylhydantoin (“BCDMH”) to the water at a level effective to control biological film-forming organisms and thereafter maintaining the BCDMH concentration at a level sufficient substantially to inhibit regrowth of such organisms.

A method of controlling biofouling in recirculating water systems for heat exchange systems without disinfecting the bulk recirculating water comprising the steps of: introducing a biocidally effective amount of 1-bromo-3-chloro-5,5-dimethylhydantoin into the water in order to kill biofouling microo

A method of controlling biofouling in recirculating water systems for heat exchange systems without disinfecting the bulk recirculating water comprising the steps of: introducing a biocidally effective amount of 1-bromo-3-chloro-5,5-dimethylhydantoin into the water in order to kill biofouling microorganisms at film-forming surfaces of the system; and thereafter maintaining the concentration of 1-bromo-3-chloro-5,5-dimethylhydantoin at a level effective to inhibit regrowth of such microorganisms at such surfaces without maintaining a continuous measurable halogen residual in the recirculating water and without disinfecting the bulk recirculating water.
