22-04: The Application of Non-Phosphorous Cooling Water Treatment Programs to Address Environmental and Operational ChallengesThere has been a recent emphasis on the development of non phosphorus (non P) cooling water treatment programs for open recirculating cooling towers that provide the necessary cooling water system performance while specifically addressing industrial needs, such as environmental and operational challenges. From an environmental perspective, phosphorus discharge regulations are becoming more stringent in various locations in the US and around the globe.

A new method of robotic cleaning helps reduce these costs by keeping tanks filled and online

and customer field trials

This plugging can reduce tower performance and in some utilities has necessitated load reduction

the theory of determining the shaft's natural frequency is presented as well as methods for empirically testing a shaft's natural frequency

and aggressive circulating water conditions

This participation of soluble silica in the development of heat-resistant films occurred at circulating water silica contents below 75 ppm

Synthetic polymers are used to control scale in cooling water systems

The heavy metals content of wastewaters is being regulated in many

The inherent challenges for a cooling tower at the site such as high summer temperature

NWD can be used as all wet cooling tower by using wet/dry lanes as wet sections

cost-effective biocide replacement for chlorine gas has long been sought

it is the choice of cooling system that frequently mediates this conflict
