80-02: Fundamental Considerations in Biofouling Control Codes and Standards

80-02: Fundamental Considerations in Biofouling Control Codes and StandardsThe term fouling refers to the formationof inorganic and or organic deposits on surfaces. In cooling systems, these deposits form on condenser tube walls increasing fluid frictional resistance, accelerating corrosion and impairing heat transfer. Biological fouling, or Biofouling, results from the attachment and growth of microbial organisms (microfouling) or microbial organisms (macrofouling). This paper is directed at microbial fouling.

Part III - Appendix: example evaluation of mechanical draft cooling tower

Cooling tower sytems using ozone with and without other treatment will be used as example

and changes in salt concentration in the droplet

Experience has taught that such changes require detailed analysis

A large semi-closed cooling water system was created ten years ago and since has had aggressive corrosion attack particularly on carbon steel surfaces

Surface analysis was used to identify passivation films and correlate their chemical composition to respective treatment and water conditions

primarily from the Shawnee Steam Plant located adjacent to the Paducah Plant

and Composite Cooling Solutions

meant to last twenty or more years

however a growing interest in employee safety by the customers

This is a piece of equipment which we prefer to be left to maintenance and operation by the heat transfer engineer
