Industrial Cooling Water Systems Waters used for recirculating cooling systems can either be scaling or corrosive. Corrosive waters are treated with corrosion inhibitors which require monitoring for overall assessment of the treatment programme.

There are many factors that affect the recirculating water actual or measured pH (pHactuai) in recirculating cooling systems. The major factors are usually considered to be the source and quality of the makeup water, the operating conditions of the cooling system, and the partial pressure of the CO2 in the air. (As the air is continually scrubbed by the cooling water, this in effect means the carbonate-bicarbonate/C02 equilibrium). 

This section is primarily concerned with the reviewing water treatment program selection process for open recirculating cooling systems and demonstrating the kind of information that may then be represented in a vendor s standard program selection guide. 

There are many open recirculating cooling systems that still do not have chemical dosing pumps available. This represents a serious risk, as the...

In open recirculating systems evaporation is the major factor in heat disposal. In these evaporative systems circulating water is continuously scrubbed with air, therefore saturated with dissolved oxygen. In contrast, water in closed recirculating cooling systems usually will contain minimum dissolved oxygen, even though the systems may include vented expansion tanks.

Ifoter supplies and treatment. Two deep wells are located on the site each one is capable of delivering the normal site demands. Water passes through reservoir tanks and is pumped from there to the Demineralizer Building. Here one portion is demineralized, another chlorinated, and a third softened and chlorinated. The reactor uses demineralized water in a recirculating cooling system. An overhead working reservoir in this loop provides the flow... 

Water in an open recirculating cooling system is characterized in comparison to make up water by the changes in some parameters due to several processes ...

Heat exchangers are chiefly made of steel but may have units made of stainless steel, brass, carbon steel and bronze-copper alloys. Four open recirculating cooling systems are operated independently. 

The containment recirculation cooling system controls building air temperature and humidity to provide a suitable environment for equipment operability during normal operation and shutdown. 

The containment recirculation cooling system is comprised of two 100 percent capacity skid mounted fen coil unit assemblies with a total of four 50 percent capacity fan coil units which connect to a common duct ring header and distribution system. 

The containment recirculation cooling system has no design requirements associated with safety.
