82-05: Controlling The Deterioration of Asbestos Cement Cooling Tower Fill Treatment ControlMany large cooling towers have been constructed over the past twenty years with asbestos cement fill. A total of forty eight power plants were surveyed as a part of this investigation. Approximately, one third of those surveyed use asbestos cement for fill or for other components (i. e., louvers, walls, etc.) of the cooling tower. At roughly half of these installations, the cooling water has caused noticeable deterioration of the fill, in two known
