The treatment of light industrial cooling water systems by high frequency, low power ultrasonic technology has proven to be an effective method to reduce, if not eliminate, the use of chemical biocides. A field study was conducted to compare the efficacy of ultrasonic technology versus conventional stabilized bromine oxidative technology as the microbiological control component of an overall cooling water treatment program. The study was conducted for a period of 12 weeks on a factory air compressor-based cooling system that uses a plate and frame heat exchanger to cool the compressor oil. Data analysis indicated significant benefits were gained through ultrasonic application. In addition to improved heat exchange, other benefits included the elimination of hazardous chemicals and a significant reduction in under-deposit corrosion potential. Control parameters and data collection protocol are described in detail.
