AB In an industrial seawater cooling system, the effects of three different antifouling treatments, viz. sodiumhypochlorite (NaClO), aliphatic amines (Mexel1432) and UV radiation, on the characteristics of the fouling formedwere evaluated. For this study a portable pilot plant, as a side-stream monitoring system and seawater coolingsystem, was employed. The pilot plant simulated a power plant steam condenser, having four titanium tubes underdifferent treatment patterns, where fouling progression could be monitored. The nature of the fouling obtained waschiefly inorganic, showing a clear dependence on the antifouling treatment employed. After 72 days the tubes undertreatment showed a reduction in the heat transfer resistance (R) of around 70% for NaClO, 48% for aliphaticamines and 55% for UV, with respect to the untreated tube. The use of a logistic model was very useful forpredicting the fouling progression and the maximum asymptotic value of the increment in the heat transferresistance (DRmax). The apparent thermal conductivity (l) of the fouling layer showed a direct relationship with thepercentage of organic matter in the collected fouling. The characteristics and mode of action of the differenttreatments used led to fouling with diverse physicochemical properties.
