15-18: Alternative to Bromine Improves Cooling Water Microbial Control and Manual

15-18: Alternative to Bromine Improves Cooling Water Microbial Control and ManualAmmonia in the cooling loop poses an additional challenge for Hypochlorite or oxidizing biocides in controlling the microbiological activity since monochloramines are not effective biocides. Historically Bromine based non oxidizing biocides have been an industry standard with occasional Isothiazolin or Gluteraldhyde dosage. This paper discusses how mixed oxidants, as a combination of hypochlorite and peroxide, generated on site replaced non oxidizing

the origin of these problems is frequently either unrelated to water chemistry

The software was developed under the open source environment Scilab/Xcos

By performing thorough annual inspections as described

economical and fully connected with today's information technology

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

Drift eliminators are commonly incorporated in wet cooling towers to reduce the amount of water droplet losses

Opportunities exist to utilize existing instrumentation in some cases along with new measurements to synthesize systems that are effective

Each type has advantages and disadvantages

operating motors on adjustable speed drives

and various other plants using steam to generate electricity

suspended swing stages

A mitigation plan consisting of intake modifications to be implemented during several phases is presented
