TYPES OF FOULING

Fouling facts

There are several different types of fouling, depending on the type of liquid used for the energy transfer and the material used in the plate heat exchanger

 

  • Particulate fouling by particles suspended in water or gas


  • Biofouling is undesirable accumulation of micro-organisms


  • Chemical fouling is the reaction on contacts with process fluids and heat transfer surface


  • Solidification fouling is when a component of flowing fluid “freezes” onto the heat transfer surface


  • Corrosion fouling is created by corrosion of the substrate like iron oxide from carbon steel


  • Precipitation – Scale formation due to dissolved substances like calcium carbonate or salts
