74-02: On the Question of Airborne Transmission of Pathogenic Organisms in HVAC ApplicationsThe siting or cooling towers on sewage polluted waters and the probable widespread use in the future of treated sewage effluent as makeup has raised the question of dispersal of pathogenic organisms in cooling tower drift. This question has public health implications and needs an answer before the environmental effects of cooJJ. ng towers can be fully evaluated. Some information pertinent to this question, e. g., the occurrence of pathogenic

The system totally utilizes all process water entering the plant and there is no waste stream discharge at the plant boundary limits

The cost of the calcium hypochlorite was relatively low

crossflow mechanical draft cooling tower was analyzed

Corrosion control is a critical factor in the maintenance of low hardness
