Aplicación de campos electromagnéticos en la eliminación y control de la película biológica en intercambiadores de calor tubulares refrigerados por agua de mar

Résumé

Biofouling is one of the more important problems of different industries on wide world, which they use to seawater system for your process or they are in contact with seawater. To avoid spending a lot of money on stops to production for cleaning of biofouling, we must to use some procedures in the fighting and control against biofouling on industrial equipment without damage to environment. The physical treatment of EMF has been researched for prevent and reduce the adhesion of biofouling on seawater cooling at heat exchangers. Results show that the application of the EMF on the cooling seawater with different variables: between 1 to 1.6 ms-1 flow velocity, different tube materials (AISI 316L and AISI 316Ti) and starting trial from clean or dirty tubes. All parameters have decreased biofouling effective in the heat exchanger around at 10 to 30% compared to the tube test (untreated).
