06-08: Realizing the Full Potential of Your Cooling Tower Lime/Soda Ash Blowdow Codes and Standards

06-08: Realizing the Full Potential of Your Cooling Tower Lime/Soda Ash Blowdow Codes and StandardsA concise and practical review of the softening process chemistry, including a review of the many chemical additive options for different influents emphasizing simplified chemistry maintenance is discussed. Several useful mechanical maintenance recommendations and chemical application modifications for often problematic operations will be provided based on long term zero discharge experiences. A "bonus" value proposition, the diversion of various

or to the operating engineer which you are sure to have

Laboratory and field case studies will be discussed

The pilot is constituted of four reduced-scale open cooling circuits (around 15 thermal kW) able to mimic the thermal and chemical behavior of an industrial cooling circuit such as those found in nuclear power plants

Another is the use of blended polymers

and instrumentation to be used for testing and evaluating the performance of evaporatively cooled

and approved as a valuable contribution to cooling tower literature

Included in the modeling are the effect of some mitigation methods such as windscreens and solid walls

Phreeqc is used for the calculation of water chemistry in each component of the circuit (chemical speciation

as well as by the droplet size distribution

These assessments assist Asset Owners with the preparation of Repair Budgets and in making enlightened decisions for these critical assets which are typically the last piece of equipment taken down before an outage and the first piece of equipment brought up after an outage

and (5) Chemical Factors

Cooling Technology in the form of Cooling Towers has been in use for decades and almost from the beginning
