Improvement of Electromagnetic Fields treatment for biofouling growth control in tubular heat exchanger-condenser cooled by seawater

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. When were not prevented or treated of water on-line, biofouling can cause a lot of problems of loss efficiency. 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 influence of flow velocity on Electromagnetic Fields treatment in stainless steel heat exchanger tubes (AISI 316Ti) cooled by seawater was evaluated based on the characteristics of the resulting biofilm that adhered to the internal surface of the tubes at flow velocities of 1, 1.2, 1.6 and 3 m/s. The results showed that the effective of Electromagnetic Fields treatment was increased at a higher flow velocity. Furthermore, the biofilm at a higher flow velocity was thinner with a lower concentration of solids and carbonate calcium, and smoother composition, which favoured the heat transfer process within the equipment.
