This article discusses the antifouling action of a continuous physical treatment process comprising the application of electromagnetic fields (EMFs) to seawater used as the refrigerant fluid in a heat exchanger-condenser to maintain the initial 'clean tube' condition. The results demonstrated that the EMFs accelerated the ionic nucleation of calcium and precipitation as calcium carbonate, which weakened the growing biofilm and reduced its adhesion capacity. Consequently, EMFs induced an erosive effect that reduced biofilm formation and fouling. This treatment allowed for the maintenance of significantly lower fouling factors in the treated tubes compared to a control group of untreated tubes, thereby leading to a higher heat transfer efficiency.
本文讨论了一种连续物理处理过程的防污作用，该过程包括对用作热交换器-冷凝器中制冷剂流体的海水施加电磁场（EMF），以维持初始的“清洁管”状态。结果表明，电磁场加速了钙的离子成核并促使其以碳酸钙形式沉淀，这削弱了正在生长的生物膜并降低了其粘附能力。因此，电磁场产生了一种侵蚀作用，减少了生物膜的形成和污垢。与未处理管的对照组相比，这种处理使处理过的管中的污垢系数显著降低，从而提高了传热效率。
