Abstract

Cooling tower water treatment is necessary because water has dissolved materials that can deteriorate the operation of the cooling tower. In addition, bacteria in the water can be scattered into the air-conditioned area that can harm people. The first known case of the outbreak of the fatal Legionnaire's disease in 1976 manifested this fact. There are several methods used in treating cooling water. The application of chemical water treatment is considered mainstream at present, however, its practice is under scrutiny because of environmental considerations. Water treatment with ozonation is selected because it is effective. It is relatively new and thought to be the least controversial of the "new" methods. Other "new" methods include magnetic and electrostatic method, etc. Additionally, many papers and reports have shown that ozonation not only cleans water but also reduces water and power consumption. This is very important especially in places where water and energy resources are not sufficient. The purpose of this paper is to perform an analysis on cooling tower water treatment according to the first and second law of thermodynamics (exergetic analysis), and try to optimize its operating conditions. The exergetic analysis is better than energetic one because it gives a clearer explanation of the performance, in particular, it takes into consideration the impact of the system on the environment.
