Treatment of Cooling Water

Pretreatment is the reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater prior to, or in leu of, discharging or otherwise introducing such pollutants into a POTW. The reduction or alteration may be obtained by physical, chemical or biological processes, process changes or by other means, except as prohibited by 40 CFR 403.6(d)

INTRODUCTION TO INDUSTRIAL WATER TREATMENT   1-1 PURPOSE AND SCOPE. This UFC provides an overview of industrial water treatment operations and management. As used in this UFC, the term “industrial water” refers to the water used in military power generation, heating, air conditioning, refrigeration, cooling, processing, and all other equipment and systems that require water for operation. Industrial water is not the same as potable water. Industrial water is never consumed or used in situations that require a high degree of sanitation. Industrial water requires water preparation or chemical treatment, or both, to avoid the problems described in paragraph 1-1.2. Water preparation and chemical treatment requirements are described in Chapters 2 through 5 according to the type of system in question. The Navy has special uses for shore-to-ship steam. The Naval Sea Systems Command (NAVSEASYSCOM) shore-to-ship steam purity standards are described in Chapter 3. Examples of industrial water systems and their uses are • Steam Boiler Systems. (See Chapter 3.) Steam uses include space and hot water heating, sterilization, humidification, indirect food processing, and power generation. • Cooling Water Systems. (See Chapter 4.) Cooling water is used in cooling towers, evaporative coolers, evaporative condensers, and once-through systems. Applications are broad, ranging from simple refrigeration to temperature regulation of nuclear reactors. • Closed Water Systems. (See Chapter 5.) These include closed hot water, closed chilled water, and diesel jacket systems.
