WebThe deposition also increases with the increasing thermal conductivity of the metal, or the total surface energy. Chemical reaction fouling along with particulate and crystallisation fouling occurred on reactive surfaces when corrosive chemicals were used, and this was compared with crystallisation-only fouling on non-reactive surfaces. WebPrecipitation fouling also occurs because of deposition of material which was originally in the fluid stream. In that respect, it is similar to particulate fouling. But in most cases of precipitation fouling, the dissolved matter in the fluid starts to precipitate due to change in fluid temperature.
