79-10: Handling Upsets in Cooling Water Systems History of Cooling TowersMuch has been written about proper treatments and controls for the protection of cooling water systems and to insure operating efficiency. The advantages of products, equipment, and programs are discussed in articles, papers, advertising and presentations by suppliers and users. these expand our knowledge of available technology and are valuable aids in optimizing cooling water treatment programs and operating efficiencies. the cooling water products,
contaminants in the waste streams frequently present new and significant challenges in corrosion control
Most of this damage could have been avoided had reasonable cold weather operating procedures been in effect
The treatment programs were evaluated on the basis of viable cell counts
