05-08: Application of low Noise Technology for Evaporative Cooling Equipment Plume AbatementReduced sound levels are becoming an increasingly critical requirement in many evaporative cooling applications. This paper will focus on the technologies such as application of alternative fan designs, reduced rotational fan speed, and attenuation to reduce fan noise and attenuation and water silencing to reduce falling water noise will be presented. The magnitude of sound reduction for each technology will be illustrated. In addition, case histories

The purpose of this document is to provide steps in preventing "white rust" through the application of appropriate water treatment programs
