...-nitrilopropionamide (DBNPA). Tests have been carried out with and without the presence of a sulfite oxygen scavenger. Sessile microorganisms were grown in biofilms on carbon steel studs and exposed to isothiazolinone at 100, 200, 300 and 400 ppm and DBNPA at 100 ppm and 200 ppm, in the presence and absence...

... magnitude nor it's cost. Corrosion alters the surface of the metal which becomes rugged. As a resulL nut threads cannot slide smoothly over stud threads. This rugged surface creates such a resistance that unfastening becomes impossible. In most cases one can define corrosion as the result of a chemical...

Recirculating biofouling loops were set up with the appropriate site water, and inoculated with the bacteria from the system so that an active biofilm was set up on small studs. These befouled studs were treated with proprietary...
